Abstract

Zirconium amides have become increasingly popular and useful due to their widespread use as precursors to other zirconium complexes and their use in the production of solid oxide fuel cells (SOFCs). Herein we report the mol-ecular structure of tris-(di-methyl-amido)-bis-(di-methyl-amine)-zirconium(IV) iodide, [Zr(C2H6N)3(C2H7N)2]I. The bond lengths and bond angles are consistent with a slightly distorted trigonal-bipyramidal coordination geometry around the metal atom. N⋯I contacts of 3.6153 (15) and 3.5922 (14) Å are consistent with the presence of N-H⋯I inter-actions. These N-H⋯I inter-actions link the complex cations and iodide anions into extended chains that propagate parallel to the a axis.

Keywords: N—H⋯I interactions; amido ligands; crystal structure; dimethylamine; iodide; zirconium.
