An optically pure P-alkene-ligated Ir(I) complex


Linden, A; Dorta, Romano (2010). An optically pure P-alkene-ligated Ir(I) complex. Acta Crystallographica. Section C, Crystal Structure Communications, 66(10):m290-m293.

Abstract

The asymmetric unit of (P)-chloridobis[(S)-(+)-5-(3,5-dioxa-4-
phosphacyclohepta[2,1-a:3,4-a0]dinaphthalen-4-yl)dibenz[b,f]-
azepine]iridium(I)–benzene–pentane (1/1/1), [IrCl(C34H22NO2P)
2]C6H6C5H12, contains two formula units. The two
symmetry-independent molecules of the Ir complex have
similar conformations and approximate C2 symmetry, with
small deviations arising from slightly different puckering of
the seven-membered dioxaphosphacycloheptadiene 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.
