摘要：

Two mononuclear cobalt(III) complexes, [Co(L-1)(N-3)(2)(deen)] (1) and [Co(L-2)(N-3)(2)(DMSO)] (2), where HL1 {2-(2-(diethylamino)ethyliminomethyl)-4-bromophenol} and HL2 {2-(2-(diethylamino)ethyliminomethyl)-6-methoxyphenol} are tridentate and tetradentate Schiff bases, respectively and deen is a bidentate chelating ligand, N,N-diethyl-1,2-diaminoethane, were prepared and characterized by elemental and spectral analysis. X-ray crystal structure determination confirmed their structures. Both complexes are meridional isomers. The solid state structures show the participation of the organic ligands in concurrent conventional and unconventional C-H center dot center dot center dot pi interactions along with hydrogen bonding. The energetic features of these interactions have also been studied by means of DFT calculations. (C) 2016 Elsevier Ltd. All rights reserved.
