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.
在双核标题化合物[η(5)-(C5(CH3)5)(CO)Fe{(μ-BCl)(μ-CO)}PtCl(P(C6H11)3)]·C6H6的分子结构中，两个金属原子，铁(II)和铂(II)，由一个羰基(μ-CO)和一个氯硼烯配体(μ-BCl)桥连。Pt(II)原子还与位于桥连硼烯反位的一个氯配体以及位于羰基配体反位的一个三环己基膦配体(PCy3)相连，在Pt(II)原子处形成一个扭曲的平面正方形结构单元。Fe(II)原子与一个五甲基环戊二烯基配体[η(5)-C5(CH3)5]和一个羰基配体(CO)相连，形成一个钢琴凳结构。此外，一个苯溶剂分子纳入晶体结构，相对于Fe(II)原子处的五甲基环戊二烯基配体呈交错排列，质心间距为3.630 (2) Å。
