Abstract

The title cyclo-metalated platinum(II) complex with 2-(4-bromo-phen-yl)pyridinato and acetyl-acetonato ligands, [Pt(C11H7BrN)(C5H7O2)], consists of two crystallographically non-equivalent dimers, each stacked by π-π inter-actions with distances of ≃ 3.4 Å. In both dimers, the platinum(II) complexes are arranged anti-parallel to each other. Each complex exhibits a slightly distorted square-planar coordination environment around the central Pt(II) atom. The dihedral angles between two chelate rings including the Pt(II) atom in these complexes are 0.08 (12) and 1.54 (9)°.

Keywords: acetylacetonato ligand; crystal structure; cyclometalated complex; platinum(II); π–π interactions.
