Abstract
Crystals of the sulfinate-containing platinate salt, (C10H9N2)2[Pt(C4N2O2S2)2], were obtained from a solution of [Pt(4,4'-bpy)2(mnt)] after a long period with minimal light (4,4'-bpy is 4,4'-bi-pyridine and mnt is maleo-nitrile-dithiol-ate). In the crystals, the cations associate via C-H⋯O hydrogen bonds with hydrogen bonded (-H⋯) chains of pyridinium anions. The cis-geometry of the sulfinate around the square-planar platinum atom, coupled with a torsion of one of the rings of the pyridinium, engenders multiple hydrogen bonds between the sulfinate oxygen atoms and the pyridinium hydrogen atoms.
