The asymmetric unit of (P)-chloridobis[(S)-(+)-5-(3,5-dioxa-4-phosphacyclo- hepta-[2,1-a:3,4-a′]dinaphthalen-4-yl)dibenz[b,f]azepine]iridium(I) -benzene-pentane (1/1/1), [IrCl(C34H22NO 2P)2]·C6H6·C 5H12, contains two formula units. The two symmetry-independent mol-ecules of the Ir complex have similar conformations and approximate C 2 symmetry, with small deviations arising from slightly different puckering of the seven-membered di-oxa-phospha-cyclo-hepta-di-ene rings. The Ir atoms have trigonal-bipyramidal coordination geometry, with the P atoms in axial positions. The steric strain of the bidentate coordination of the P-alkene ligand through its P and alkene C atoms causes the N atom to have pyramidal geometry, compared with the trigonal-planar geometry observed in the free ligand. The coordination also results in an anti conformation of the binaphthyl and alkene groups within the P-alkene ligand.
