Crystal and molecular structure of chloro{methyldi-[(6-methyl-2-pyridyl)methyl]amine}palladium(II) chloride

Abstract

Crystals of the title compound are orthorhombic, space-group Cmc2₁, Z= 4, in a unit cell of dimensions a= 13·648(9), b= 13·156(11), c= 8·772(8)Å. The intensities of 1115 independent reflections above background collected by counter methods were refined to R 0·042. The palladium atom is in a distorted square planar environment, the chlorine atom being 0·93 Å out of the plane containing the palladium and three nitrogen atoms. The Pd–Cl bond distance is 2·331 (3)Å. The Pd–N(tertiary) bond distance [2·018(8)Å] is significantly shorter than the Pd–N(pyridine) distances [2·068(6)Å]. The preparation of the analogous bromo-complex is also given together with i.r. and n.m.r. spectral data for the two complexes.
