Dichlorotriethylphosphine-[N Platinum(II)

Abstract

By treatment of 1,3-bis(3,4-dimethoxybenzyl)-3,4,5,6-tetrahydropyrimidinium chloride (1) with KOBu t and [PtCl<inf>2</inf>(PEt<inf>3</inf>)<inf>2</inf>]<inf>2</inf> N-coordinated platinum complex (2) is obtained. The Pt atom is coordinated in square planar arrangements by two chloride ions in a trans-configuration, the N-formyl-N,N′-bisaryltrimethylenediamine nitrogen atom, and the phosphine P atom. An extensive three-dimensional network of three C-H...O hydrogen bonds, two C-H...π and one π...π interactions are responsible for the crystal stabilization. Intermolecular hydrogen bonds and C-H...π interactions produce R <inf>2</inf> 2 (6), R <inf>2</inf> 2 (22), R <inf>2</inf> 2 (24), R <inf>3</inf> 3 (23), R <inf>4</inf> 4 (26), and R <inf>4</inf> 4 (32) rings. © 2014 Pleiades Publishing, Ltd.
