Abstract: | Bis(μ‐3,11‐diethyl‐6,8‐diphenyl‐3,6,8,11‐tetraphosphatridecane‐κ4P3,P6:P8,P11)dirhodium(I) bis(tetrafluoroborate), [Rh2(C25H40P4)2](BF4)2, is a bimetallic complex containing two binucleating tetra‐tertiary phosphine ligands. The distance between the metal centers is 5.4555 (11) Å, with no metal–metal bond. The Rh—P bond distances range from 2.2483 (14) to 2.3295 (14) Å. The geometry about the RhI atoms is tetrahedrally distorted square planar and the dihedral angle between the two coordination planes is 66.28 (5)°. |
