A series of thorium nitrate complexes with some schiff bases derived from substituted benzaldehydes and amino compounds has been synthesised and characterised.The schiff bases employed are N-(3-methoxy-4-hydroxybenzylidene)isonicotinylhydrazone (MHBIN), N-(3-methoxy-4-hydroxybenzylidene)benzhydrazone (MHBBH), N-(3-methoxy-4-hydroxybenzylidene)salicyloylhydrazone (MHBSH), N-(3-methoxy-4-hydroxybenzylidene)anthranilic acid (MHBAA), 4-N-(3-methoxy-4-hydroxybenzylidene)aminoantipyrine (MHBAAP), 1,2-N,N-(3-methoxy-4-hydroxybenzylidene)phenylenediamine (MHBPDA), N-(3,4-dimethoxybenzylidene)isonicotinylhydrazone (DMBIH), N-(3,4-dimethoxybenzylidene)benzhydrazone (DMBBH), N-(3,4-dimethoxybenzylidene)salicyloylhydrazone (DMBSH), N-(3,4-dimethoxybenzylidene)anthranilic acid (DMBAA), 4-N-(3,4-dimethoxybenzylidene)aminoantipyrine (DMBAAP) and 1,2-N,N-3,4-dimethoxybenzylidene)phenylenediamine (DMBPDA).Elemental analysis and molecular weight data of the complexes indicate that they have composition ThL2(NO3)4 (L = MHBIH, MHBBH, MHBSH, MHBAA, MHBAAP, DMBIH, DMBBH, DMBSH, DMBAA and DMBAAP) and ThL(NO3)4 (L = MHBPDA and DMBPDA).IR spectral and conductance data show that all the ligands act as neutral bidentate ones and nitrate groups are coordinated to the metal ion in a monodentate fashion.
