Abstract
New series of complexes of general formula [OsL(Cl)2(H2O)2].nH2O
; where LH=[alpha-(2-hydroxy-1-naphthyl)-N-(para-R-phenyl nitrone] , n=number of the crystallization water(0-6)
and R=H, Cl , Br , COCH3 , NHCOCH3 , NH2 and CH3 were synthesized . The
complexes were synthesized from direct reaction of the osmium(III) chloride
with ligand (L) in a molar ratio of 1:1 respectively. These complexes were
characterized by several physical methods such as melting points, molar
conductance and elemental analysis(CHN),magnetic moments as well spectral such
as infrared and electronic spectral measurements. These studies revealed that the
Ligand (L) was behaved as a bidentate,
univalent and coordinated to the osmium(III) ion through the oxygen atoms of
both , the hydroxyl and the nitrone
groups, as well, the presence of two chloride ions and two aqua molecules to
give the most probable octahedral geometry around each osmium ion in each
complex. The elemental analysis(CHN) as well the infrared spectra showed the
presence crystallization water molecules outside the coordination sphere. Their
molar conductance measurements revealed the non-electrolytic behavior of the
synthesized complexes.
