Abstract
In the title complex, [CoPd2(C3H5)2(C8H11)Cl2(C40H30P2)]·CH2Cl2, the CoI atom is sandwiched between the cyclopentadienyl and cyclobutadiene rings. The two diphenylphosphine substituents of the cyclobutadiene ring are situated opposite to each other and bind two PdII atoms, which are additionally coordinated by a chloride ion and the three C atoms of an allyl ligand, forming a distorted planar coordination environment. The Cl atoms of the dichloromethane solvent molecule (equal occupancies) and one C atom and its attached H atom of each of the allyl ligands (occupancies 0.55:0.45) are disordered.
