(Bipyridyl-N,N')diiodoplatinum(II)

Abstract

Square-planar (bipyridyl-N,N')diiodoplatinum(II), [PtI_2(C_(10)H_8N_2)], has normal Pt--N(bipyridyl) [2.029 (7) Å] and Pt--I bonds [2.589 (2) Å]. The bipyridyl ligand exhibits normal distances and angles. Because of steric effects, the intramolecular I...I separation [3.587 (1) Å] and the corresponding I--Pt--I angle [87.7 (1)°] are significantly smaller than those observed for other cis-bis(iodo)bis(N-donor) complexes. The parallel square-planar units stack to form a chain structure. Relative lateral displacement of consecutive molecules along a chain results in a Pt..-Pt distance [5.291 (1) Å] considerably longer than the interplanar spacing [3.510 (11) Å].
