Abstract

Two new isostructural octahedral complexes [CoX(H2O)(salophen)]·H2O·EtOH (X=Cl (1), Br (2); salophen=N,N′-bis(salicylidene)-1,2-diaminobenzene) have been prepared by reaction of CoX2 and H2salophen in a mixture of ethanol and dichloromethane (1:1) and characterized by IR spectroscopy and elemental analysis. Crystal structures of both 1 and 2 are molecular and built up of [CoX(H2O)(salophen)] complex molecules and solvate water and ethanol molecules. The salophen ligand occupies the equatorial plane of the hexacoordinated Co(III) atom while halogenido and aqua ligands are placed in the axial positions. The crystal packings are formed by O–H···O hydrogen bonds and additional π–π stacking interactions. The results of thermogravimetric studies of 1 and 2 revealed that the loss of solvating molecules takes place first.

Keywords: Co(III) complex; crystal structure; isostructurality; Schiff base; thermal properties
