Crystal structure of μ-1κC:2(η2)-carbonyl-carbonyl-1κC-chlorido-2κCl-μ-chloridoborylene-1:2κ2B:B-[1(η5)-pentamethylcyclopentadienyl](tricyclohexylphosphane-2κP)iron(II)platinum(II) benzene monosolvate

Abstract

In the molecular structure of the dinuclear title compound [η5-(C5(CH3)5)(CO)Fe{(μ-BCl)(μ-CO)}PtCl(P(C6H11)3)]·C6H6, the two metal atoms, iron(II) and platinum(II), are bridged by one carbonyl (μ-CO) and one chloridoborylene ligand (μ-BCl). The PtII atom is additionally bound to a chloride ligand situated trans to the bridging borylene, and a tricyclohexylphosphane ligand (PCy3) trans to the carbonyl ligand, forming a distorted square-planar structural motif at the PtII atom. The FeII atom is bound to a pentamethylcyclopentadienyl ligand [η5-C5(CH3)5] and one carbonyl ligand (CO), forming a piano-stool structure. Additionally, one benzene solvent molecule is incorporated into the crystal structure, positioned staggered relative to the pentamethylcyclopentadienyl ligand at the FeII atom, with a centroid–centroid separation of 3.630 (2) Å.
