چکیده
In the title compound, [Ni(2)(C(2)H(4))(2)(C(25)H(22)P(2))(2)]·2C(7)H(8), each Ni atom is coordinated in a trigonal-planar geometry by two P atoms of the bridging 1,2-bis-(diphenyl-phosphino)methane (dppm) ligands and by the centroid of the double bond of an ethene ligand. An eight-membered ring comprising the two Ni atoms, four P atoms and the CH(2) groups of the two dppm ligands is thus formed. The methyl group in one of the solvent toluene mol-ecules is disordered over two positions with equal occupancies.
