Bis[N,N-bis(diphenylphosphanyl)pentylamine-κ²P,P′]platinum(II) bis(hexafluoridophosphate) dichloromethane disolvate

Abstract

The PtII atom in the title compound, [Pt(C29H31NP2)2](PF6)2·2CH2Cl2, is coordinated by four P atoms from two bis­(di­phenyl­phosphan­yl)pentyl­amine ligands with an average Pt—P distance of 2.300 (1) Å. The coordination around the PtII atom shows a highly distorted square-planar geometry, as evidenced by the P—Pt—P bite angles of 70.45 (3) and 70.64 (3)°. The asymmetric unit contains two hexa­fluoridophosphate ions, the metal complex and two dichloro­methane solvent mol­ecules. One of the chloride atoms of one of the dichloro­methane mol­ecules is disordered over two sites in a 0.515 (3):0.485 (3) ratio. C—H⋯F hydrogen bonds stabilize the crystal packing.

Crystal structure of N,N-bis(diphenylphosphanyl)cyclohexylamine, C30H31NP2

“…The modular structure of the ligands enables "tuning" of the catalyst activity and selectivity through systematic variation of the donor atoms, their substituents, and the ligand backbone framework. There are numerous examples of crystal structures of such PNP-pincer ligands [1][2][3][4][5][6] and metal complexes [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Diphosphinoamine (PNP) and other P donor ligands [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] with various substituents on both the P and N atoms have been applied to several catalytic reactions such as methoxycarbonylation [17], metathesis [18], hydroformylation [19] and C-H activation [24].…”
