A few oxomolybdenum(V) and dioxomolybdenum(VI) complexes-of schiff bas
es derived from 4-aminoantipyrine and salicylaldehyde (AAPySAL), 2-hyd
roxy-1-naphthaldehyde (AAPyNAL), furan-2- aldehyde (AAPyFAL), 4-dimeth
ylaminobenzaldehyde (AAPyDAB) of the type [(MoOLCl2)-Cl-1], [(MoOLCl2)
-Cl-2], (L-1 = AAP/SAL, L-2 = AAPyNAL), [MoOL21 (NCs)CL], [MoOL2 (NCS)
CL2], [(MoOLCl3)-Cl-3] (L-3 = AAPyFAL); [MoOL3 (NCS)Cl-2], [MoOL4 (NCS
)(2)Cl] (L-4 = AAPyDAB) and [MoO2 L-1 (NCS)Cl], [MoO2 L-3 (NCS)Cl] wer
e prepared and characterised by elemental analysis, IR, electronic and
ESR spectra, and, magnetic and conductance studies. The X-ray powder
pattern of the complex [MoO (AAPySAL)Cl-2] has been examined and found
to be orthorhombic with unit cell. dimensions, a=10.21 Angstrom, b=14
.07 Angstrom and c=15.12 Angstrom. The number of molecules per unit ce
ll was found to be four.
