title: Crystal structure of μ-1κC:2(η(2))-carbonyl-carbonyl-1κC-chlorido-2κCl-μ-chlorido-borylene-1:2κ(2) B:B-[1(η(5))-penta-methyl-cyclo-penta-dien-yl](tri-cyclo-hexyl-phosphane-2κP)iron(II)platinum(II) benzene monosolvate.
abstract: In the mol-ecular structure of the dinuclear title compound [η(5)-(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 chlorido-borylene ligand (μ-BCl). The Pt(II) atom is additionally bound to a chloride ligand situated trans to the bridging borylene, and a tri-cyclo-hexyl-phosphane ligand (PCy3) trans to the carbonyl ligand, forming a distorted square-planar structural motif at the Pt(II) atom. The Fe(II) atom is bound to a penta-methyl-cyclo-penta-dienyl ligand [η(5)-C5(CH3)5] and one carbonyl ligand (CO), forming a piano-stool structure. Additionally, one benzene solvent mol-ecule is incorporated into the crystal structure, positioned staggered relative to the penta-methyl-cyclo-penta-dienyl ligand at the Fe(II) atom, with a centroid-centroid separation of 3.630 (2) Å.
