Sažetak
By reaction of the enantiomerically pure 7-bromo-1,3-dihydro-1-methyl-3(S)-methyl-5-(2'-pyridyl)-2H-1,4-benzodiazepin-2-one, (+)-1, with CuCl2 ∙ 2H2O in a mixture of absolute ethanol and dichloromethane, dichloro-[7-bromo-1,3-dihydro-1,3-dimethyl-5-(2'-pyridyl)-2H-1,4-benzodiazepin-2-on-N,N,O]copper(II), (±)-2, was obtained. In both structures, the characteristic boat conformation of the seven-membered benzodiazepine ring was observed. Complex 2, which was isolated as a racemic compound, revealed a slightly distorted trigonal bipyramid. Copper(II) was coordinated by two azometine nitrogen atoms, two chlorine atoms and the lactam oxygen of a neighbouring molecule. In this way, an infinite chain of complex molecules was formed in the crystal. The chemical behaviour of ligand 1 upon CuII coordination was compared with its 3-hydroxymethyl and 3-acetoxymethyl analogues.
