Tetrazoles and tetrazole complexes. Part I. Crystal structure of cis-bis[dimethyl(phenyl)phosphine]bis-(5-methyltetrazolato)palladium(II)

Abstract

Crystals of the title compound are orthorhombic, a= 16·265, b= 10·545, c= 13·939, space-group P212121 with with Z= 4. The structure was refined by full matrix least-squares methods to R 0·042 for 1461 statistically significant reflections measured on a diffractometer. A distorted cis-square planar configuration is found around the palladium atom. If phenyl groups are excluded, a pseudo-two-fold axis exists along the line bisecting the two sets of nitrogen and phosphorus ligands. Both tetrazole rings are N(1) bonded, planar and almost regular pentagons with mean bond lengths of 1·33 A. There are no unusually short intermolecular distances.
