Crystal structure of bis(μ2-5-nonanoylquinolin-8-olato)bis[aquadichloridoindium(III)]

Abstract

Crystallization of 5-nonanoyl-8-hydroxyquinoline in the presence of InCl3 in acetonitrile yields a dinuclear InIII complex crystallizing in the space group P\overline{1}. In this complex, [In2(C18H22NO2)2Cl4(H2O)2], each indium ion is sixfold coordinated by two chloride ions, one water molecule and two 8-quinolinolate ions. The crystal of the title complex is composed of two-dimensional supramolecular aggregates, resulting from the linkage of the Owater—H...O=C and Owater—H...Cl hydrogen bonds as well as bifurcated Carene—H...Cl contacts.
