Synthesis and spectral analysis of oxomolybdenum (V) and dioxo-molybdenum (VI) complexes of schiff bases derived from 1,2-dihydro-1,5-dimethyl-2-phenyl-4-amino-3H-pyrazol-3-one

Abstract

A few oxomolybdenum(V) and dioxomolybdenum(VI) complexes of schiff bases derived from 4-aminoantipyrine and salt-cylaldehyde (AAPySAL), 2-hydroxy-1-naphthaldehyde (AAPyNAL), furan-2-aldehyde (AAPyFAL), 4-dimethylami-nobenzaldehyde (AAPyDAB) of the type [MoOL¹CI₂], [MoOL²CI₂] (L¹ = AAPySAL, L² = AAPyNAL), MoOL_2I(NCS)CL] [MoOL₂ (NCS)CL₂], [MoOLJCl)] (L₃ AAPyFAL; [M OL₃ (NCS)CI₂], [MoOL₄ (NCShCl] (L4 AAPyDAB) ant [MoO₂ L^I (NCS)Cl], [MoO₂ L₃ (NCS) CI] were prepared a d characterised by elemental analysis, IR, lectronic and ESR s ectra, and, magnetic and conductance studies. The X-ray power pattern of the complex [MoO (AAPySA )CI₂] has been examined and found to be orthorhombic with unit cell dimension ,<em>a</em> = 10.21 &Aring;, <em>b</em>= 14.07 &Aring; and c=15.12 &Aring;. 111 number of molecules per unit cell was found to be four.
