PREPARATION, PROPERTIES, AND MOLECULAR STRUCTURE Of trans-DICYANO BIS[BIS(DIPHENYLPHOSPHINO) METHANE]PALLADIUM (Ⅱ)

引用

Chinese Journal of Structural Chemistry 1992年第1期 20-23页

作者： Selbin J. fronczek f.R. Baton Rouge U. S. A. Department of Chemistry. Louisiana State University LA 70803

The crystal structure of the title compound has been determined. PdC52H44N2P4, Mr = 927. 2, monoclinic, space group P21 /n, a =12. 102(2), b = 9.997(2), c=20. 254(5)(?),β=93. 80(2)°, V = 2445. 0(?)3, Z = 2, R =0. 075 and Rw = 0. 095 for 3535 observed reflections (I>3σ(I)), The palladium atom is located on the symmetric center and adopts a square planar coordination surroundings with two biphosphine ligands and two cyanide groups. The molecular structure in crystals is different from that in solution in which the molecule is very fluxional, probably due to the rapid alteration in coordination sites between the coordinated and uncoordinated phosphorus atoms of the biphosphine ligands. Their properties are also reported.

SYNTHESIS AND CRYSTAL STRUCTURE Of A HETERODINUCLEAR COMPLEX Of PALLADIUM SILVER WITH BRIDGING BIS-( DIPHENYLPHOSPHINO ) METHANE [ 1 ]

引用

Chinese Journal of Structural Chemistry 1990年第2期 154-158页

作者： f.R.fronczek,J.Selbin Department of Chemistry Louisiana State University Baton Rouge Louisiana 70803 U.S.A. Department of Chemistry Louisiana State University Baton Rouge Louisiana 70803 U.S.A.

A heterodinuclear complex, trans- dicyano- palladium (Ⅱ)- bis [β- bis (diphenylphosphino)methane]-nitritosilver(Ⅰ),has been prepared by treatment of trans-(NC)2Pd(dppm)2 with AgNO2 and characterized by elementary analysis, ir, nmr, and X-ray crystal structure determination. AgPdC52H44N3O2P4,Mr= 1081. 12,monoclinic,space group P21/c,a=14. 745(7),b= 19. 208(7),c= 17. 486(6) A ,β=94. 99°(2) ,and Z = 4. The final R=0. 032 for 8673 unique reflections. In the molecule,the Pd -Ag distance is 3. 205 A. The palladium moiety has an approximately square planar geometry, and the silver moiety has a severely distorted tetrahedral geometry.
