The structural characterization of Re2Cl4(μ-dcpm)2 (dcpm = Cy2PCH2PCy2) and a new crystallographic form of Re2Cl4(μ-dppm)2 (dppm = Ph2PCH2PPh2)

The single crystal X-ray structures of the triply bonded complexes Re2Cl4(μ-dcpm)2 (1) (dcpm = Cy2PCH2PCy2) and a new crystal form of Re2Cl4(μ-dppm)2 (2) (dppm = Ph2PCH2PPh2) have been determined and are compared with literature data for other complexes of this type. Complexes 1 and 2 both possess staggered rotational geometries. Complex 1 has Re-Re distances of 2.2256(4) and 2.2267(4) A? for two crystallographically independent molecules. Complex 2 also has two independent molecules in the asymmetric unit, one of which is normal with Re-Re = 2.2497(4) A?, whereas the other exhibits a twofold orientational disorder for the Re-Re unit (distances 2.2368(5) A? and 2.231(4) A? for the major (90%) and minor (10%) forms respectively).

Structural characterization of the triply bonded dirhenium(II) complexes Re2Cl4(μ-Ph2PCH2PPh 2)2 and α-Re2Cl4(Me2P(CH2) 2PMe2)

The complexes Re2Cl4(LL)2, where LL are the bidentate ligands Ph2PCH2PPh2 (dppm) (1) and Me2P(CH2)2PMe2 (dmpe) (2), which both possess the electronic configuration σ2π4δ2δ*2 and thus formally a metal-metal triple bond, have been structurally characterized by X-ray crystallography. Re2Cl4(dppm)2 (1): Re2Cl4P4C50H44; monoclinic, P21/n; a = 11.647 (3) A?, b = 12.849 (4) A?, c = 38.691 (9) A?, β= 85.96 (2)°, V = 5776 (43) A?3, Z = 4. The molecule has two dppm molecules spanning the Re-Re bond. The two fused five-membered rings assume twist-boat conformations, leading to a completely staggered arrangement of the substituents on the two rhenium atoms. The average Cl-Re-Re-Cl torsion angle is 56 [1]°, and the Re-Re bond length is 2.234 (3) A?. Re2Cl4(dmpe)2·CH3OH (2) was isolated and crystallized as the α isomer, viz., with the dmpe ligands chelating. The crystallographic parameters are as follows: Re2Cl4P4OC13H36; orthorhombic, Ccma (nonstandard setting of Cmca); a = 11.595 (2) A?, b = 14.475 (2) A?, c = 14.925 (2) A?, V = 2505 (1) A?, Z = 4. The dimetallic unit has a Re-Re bond length of 2.264 (1) A and an eclipsed conformation with the geminal chlorides in a cis configuration. The five-membered chelate rings have envelope conformations.
