New metal complexes with di(mono)acylhydrazidate molecules.
The simple hydrothermal self-assemblies between metal salts, organic polycarboxylic acids and N(2)H(4)·H(2)O, sometimes in the presence of phenanthroline (phen), created four di(mono)acylhydrazidate-coordinated compounds [Pb(2)(DPHKH)(2)(phen)(2)]·2H(2)O 1, [Cd(ODPTH)(phen)]·0.25H(2)O 2, [Pb(2)(MPTH)(4)(phen)(2)] 3, [Cd(2)(MPTH)(4)(phen)(2)]·H(2)O 4 as well as one diacylhydrazide molecule [H(2)(ODPTH)] 5 (DPHKH = 4,4'-diphthalhydrazidatoketone hydrazone, MPTH = 3-methylphthalhydrazidate, ODPTH = 4,4'-oxydiphthalhydrazidate). Note that the di(mono)acylhydrazidate molecules in the title compounds originated from the in situ acylation reactions between organic polycarboxylic acids and N(2)H(4)·H(2)O. Interestingly, another kind of ligand in situ reaction was found in the formation process of DPHKH in compound 1: the nucleophilic addition reaction of a ketone with N(2)H(4)·H(2)O.
