SYNTHESIS AND CHARACTERISATION OF µ-OXY-BIS [TRIARYLANTIMONY (V)] DICARBOXYLA...IJSIT Editor
Several hitherto to unknown µ-oxybis[triarylantimony(V)]dicarboxylates & µ-oxy-
bis[triarylantimony]halo-carboxylates of the general formula R3Sb(L)-O-Sb(L)R3 & R3Sb(Cl)-O-Sb(L)R3 respectively
have been synthesised by the metathetical reactions of µ-oxybis(triarylantimony)dichloride reactions and silver salts
of corresponding carboxylic acids in 1:2 & 1:1 ratio [where L= 2-pyrazine carboxylic acid, p-methoxy medallic acid,
salicylic acid, benzillic acid, )]. The newly synthesised antimony derivatives have been characterised on the basis of
melting point, elemental analysis, IR
IH &
13C NMR spectra. The molecular weight & conductivity data indicate the
monomeric & non electrolytic behaviour in solution, these have been found to exhibit moderate to significant
antimicrobial activity.
Spectral studies of 5-({4-amino-2-[(Z)-(2-hydroxybenzylidene) amino] pyrimidi...IOSR Journals
Some transition metal ions Complexes with 5-({4-amino-2-[(Z)-(2-hydroxybenzylidene) amino]
pyrimidin-5-yl} methyl)-2,3,4-trimethoxybenzene were prepared and characterized by elemental analyses,
Infrared , magnetic moment, electronic spectra , mass spectra, X-ray powder diffraction, molar conductance
and thermal analysis (TGA). The complexes have general formulae [ML2.2H2O] {where M = Mn (II), Co (II), Ni
(II), Cu (II), Zn (II), Pd (II) and Pt (II). The coordination behavior of the metal ions towards to the investigated
Schiff base takes place through –C=N,-NH2 and –OH groups. The obtained C, H and N elemental analysis data
showed the Metal: Ligand ratio is 1:2 [M: L] ratio. The molar conductance data reveal that all the metal
complexes are non-electrolytic in nature. From the magnetic moments the complexes are paramagnetic except
Zn metal ion complexes have octahedral geometry with coordination number eight. The thermal behavior of
these complexes shows that, the hydrated complexes have loses two water molecules and immediately followed
by decomposition of the anions and ligand molecules in the second and third stage. The Schiff bases and metal
complexes show good activity against some bacteria. The antimicrobial results indicate that, the metal
complexes have better antimicrobial activity as compared to the prepared Schiff base.

Synthesis, Physicochemical Characterization and Structure Determination of So...IOSR Journals
Some novel nickel(II) complexes with the ligand (z)-4-((2-hydroxy-3-
methoxyphenyl)diazenyl)-1,5-dimethyl-2-phenyl-1H-pyrazol-3-(2H)-one,GAAP,guiacolazoantipyrine, L
having molecular formulae [Ni(L)2X2] and [Ni(L)2(NCS)Cl] where X = Cl-, Br-, NO3
- were synthesized and
characterized. The elemental analysis, Spectral (IR, UV-Visible, EPR, FAB – mass) studies and thermo
gravimetric analysis reveals that the Ni(II) is six coordinated in its complexes. A rhombic symmetry can be
tentatively proposed for the complexes. The magnetic susceptibility measurements show that the complexes are
paramagnetic in nature. The powder XRD study shows its anisotropic nature

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
