Crystal and molecular structures of dichloro[bis(diphenylphosphino)methane]palladium(II), dichloro[bis(diphenylphosphino)ethane]palladium(II), and dichloro[1,3-bis(diphenylphosphino)propane]palladium(II)

Hydrolysis of chlorophosphine ligands on platinum and palladium. 31P and 195Pt nmr studies and the crystal and molecular structures of cis-[PtCl2(PPh2OH)2]•C4H8O and [Pd2(µ-Cl)2{(P(OEt)2O)2H}2]

“…The t w~ square planar palladium centres are sepafated by 3.488(1) A and the Pd-Cl bonds average 2.393 A which are normal distances for a bridged system without metal-metal interaction (25a). The Pd-P bonds average 2.220 A, consistent with the low trans influence of chlorine (26)(27)(28) Tables 1 to 7, the Results section, and in the preparative descriptions below. Microanalysis was by the Canadian Microanalytical Service, Vancouver, B.C., Canada.…”

Structures of Pd[(PPh2)2(NMe)]Cl2, Pt[(PPh2)2(NMe)]Cl2 and Pt[(PPh2)2(NMe)](CN)2

“…The differences in the M--X bond lengths in (1) and (3) are ascribed to packing effects. The average value of 2.361 (1)/~ for the Pd--C1 bond length in (1) is comparable to the values observed for the complexes Pd[(PPh2)2NEt]C12 (Mokuolu, Payne & Speakman, 1973) and Pd[dppm]C12 (Steffen & Palenik, 1976). The C1--Pd--C1 angle in (1), 95.89 (4) °, is equivalent to the value reported for the complex Pd[(PPh2)2NEt]C12 and just significantly higher than the angle reported for Pd[dppm]C12.…”

2-[2,2-Bis(diphenylphosphanyl)ethylsulfanyl]phenylamine (NSPP), a new hetero-bifunctional ligand and its PdCl2 complex

“…Related bonding patterns are similar to those found in other diphenylphosphanylalkane chelate structures conraining the PdP2C ring (Davies, Pinkerton, Syed & V'tlmer, 1988;Palenik, Mathew, Steffen & Beran, 1975;Steffen & Palenik, 1976;Wink, 1990). They display almost the same ring angles (P--Pd--P average.73.2, P--C--P average 93.5 and Pd--P--C average 94.8°).…”
