Nickel(II) complexes of imine ligands derived from 7-formylindoles
Abstract
Quadridentate bis-imine nickel(II) complexes have been formed from 7-formylindoles and 1,2-diamnobenzene: an X-ray crystal structure determination of the chloroform solvate of the N,N′-bis(4,6-dimethoxyindol-7-ylidene)-1,2-diaminobenzene complex shows severe distortion from planarity and a distance of 2.96 Å between the C-2 indole atoms.
