[Bis(diphenylphosphino)amine-?2P,P'][1, 3-bis(diphenylphosphino)propane-?2P,P']platinum(II) dichloride dichloromethane solvate

The title complex, [Pt(C24H21NP2)(C 27H26P2)]Cl2·CH 2Cl2 or [Pt(dppa)(dppp)]Cl2·CH 2Cl2, where dppa is bis(diphenylphosphino)amine and dppp is l,3-bis(diphenylphosphino)propane, has two different chelate rings. The PtII atom has a distorted square-planar geometry. The six-membered chelate ring of dppp has a chair conformation. There is a hydrogen bond between the dppa N - H group and a Cl- counter-ion. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
