Abstract

In the title compound, [PtCl(C27H35N3)]Cl·C7H8, the PtII atom is coordinated in a pseudo-square-planar fashion by the N atoms of a 4,4′,4′′-tri-tert-butyl-2,2′:6′,2′′-terpyridine (tbtrpy) ligand and a Cl atom. The Pt—N distance of the N atom on the central pyridine is 1.941 (4) Å, while the peripheral N atoms have Pt—N distances of 2.015 (4) and 2.013 (4) Å. The Pt—Cl bond distance is 2.3070 (10) Å. The cations pack as dimers in a head-to-tail orientation with an intermolecular Pt⋯Pt distance of 3.2774 (3) Å and Pt⋯N distances of 3.599 (4), 3.791 (4) and 4.115 (4) Å. The solvent molecule is disordered and occupies two positions with a ratio of 0.553 (6):0.447 (6).

Highlights

In the title compound, [PtCl(C27H35N3)]ClC7H8, the PtII atom is coordinated in a pseudo-square-planar fashion by the N atoms of a 4,40,400 -tri-tert-butyl-2,20 :60,200 -terpyridine ligand and a Cl atom
The cations pack as dimers in a head-to-tail orientation with an intermolecular Pt Pt distance of 3.2774 (3) Å and Pt N distances of 3.599 (4), 3.791 (4) and 4.115 (4) Å
The bond distances and angles around the platinum atom in the title structure are all similar to the structures of the perchlorate (Lai, et al, 1999) and tetrafluoroborate salts (Batrice et al 2010) of the [(tbtrpy)PtCl]+ complex
