چکیده
The crystal structure of the title compound, [Cu(C(26)H(22)P(2))(2)][CuCl(2)], is composed of discrete Cu(dppey)(2)](+) cations [dppey is cis-bis-(diphenyl-phosphino)ethene] and [CuCl(2)](-) anions. The tetra-hedral Cu(P-P)(2) core of the [Cu(dppey)(2)](+) cation is distorted, with Cu-P bond lengths ranging from 2.269 (1) to 2.366 (1) Å. The five-membered -Cu-P-CH=CH-P- rings adopt envelope conformations, with the Cu atom lying 0.38 and 0.65 Å out of the P-C=C-P planes. The Cu-Cl distances in the [CuCl(2)](-) anion are 2.094 (2) and 2.096 (2) Å, with a Cl-Cu-Cl angle of 176.81 (7)°.

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 forme...
