Abstract

A series of three platinum (II) bisphosphine complexes 1-3 [Pt(1-(SO₂),8-(O)-nap)(PR₃)₂] (where R₃ = Ph₃, Ph₂Me, Me₂Ph) have been prepared by metathesis from cis-[Pt(PR₃)₂Cl₂)] and the dilithium salt of 1,8-naphthosultone. The novel compounds were fully characterised by X-ray crystallography, multinuclear NMR, IR and MS. The molecular structures of 1-3 were compared by measuring the peri-distance, splay angle magnitude, peri-atom displacement, naphthalene ring torsions, aromatic ring orientations and the geometry around the platinum centre. The platinum metal adopts a distorted square planar geometry in all three complexes which causes deformation of the naphthalene system. The degree of molecular deformation does not decrease upon going from 1 to 3 as anticipated, instead a competition between steric effects and intramolecular interactions causes 3 to display distortion intermediate of 1 and 2.
