Structural characterization of an ordered crystalline modification of [In(SePh)3]∞

Abstract

A triclinic modification of [In(SePh)₃]_∞ has been structurally characterized by X-ray diffraction, demonstrating that it is chemically distinct from a previously reported monoclinic form. Thus, triclinic [In(SePh)₃]_∞ is crystallographically ordered and contains five-coordinate trigonal bipyramidal indium centers with asymmetrically bridging [SePh] ligands, whereas the monoclinic form is disordered and contains six-coordinate octahedral indium centers with symmetrically bridging [SePh] ligands.
