title: A 1,2,4-diazaphospholane complex of rhodium.
abstract: The crystal structure of a prospective olefin catalyst, namely [2-[1-acetyl-5-(2-hydroxyphenyl)-4-phenyl-1,2,4-diazaphospholan-3-yl]phenyl acetate-kappaP]chloro(eta(4)-cycloocta-1,5-diene)rhodium(I) dichloromethane solvate, [RhCl(C(8)H(12))(C(24)H(23)N(2)O(4)P)].CH(2)Cl(2), has been determined at 173 K. The five-membered heterocycle of the phosphine ligand is in a slightly distorted twist conformation. An intramolecular N1-H1.Cl1 hydrogen bond contributes to the adopted conformation and may additionally participate in secondary interactions with substrates during catalysis.
