Abstract

The X-ray structure analysis of [Et2In(μ,λ-O2C) -C6H4-2-NH2]n(1) reveals an extended one-dimensional chain comprised of an array of five-coordinate indium centers. The chain unit repeated along two-fold screw axis is defined by the diethylindium moiety chelated asymmetrically by the carboxylate group with one of the two carboxylate oxygens acting as bridge to the next indium center in the chain. The NH2group does not participate in the coordination of the metal center but is involved in an intermolecular hydrogen bond. © 2000 Elsevier Science S.A.
