Tri-μ-chloro-hexakis(dimethylphenylphosphine)diruthenium(II) hexafluorophosphate

Abstract

Abstract. [Ru2C13(PMe2Ph)6]PF6, Ru2ClaPTF6C48H66, M=1282. Monoclinic, P21/c, a=14.43 (1), b=16.41 (1), c=23-86 (2)A, fl=97.5 (1) °, V=5601 A 3, Dm= 1"55 (1), Dc=1"53 g cm -3, Z=4, /z=9"25 cm -1. R= 0.069 for 4983 observed data; two Ru, seven P and three C1 atoms anisotropic. The Ru atoms are approximately octahedrally coordinated: Ru...Ru= 3.39, Ru-C1 range from 2.46 to 2.52, Ru-P from 2.28 to 2.30 A; average Ru-CI-Ru = 86 °.

The structure of the orange complex [Ru(S2CH)(PMe2Ph)4]PF6: dithioformato[tetrakis(di-methylphenylphosphine)]ruthenium(II) hexafluorophosphate

“…The pattern of Ru-P lengths is as expected: the trans diaxial pair (2.42, 2.43 A) are significantly longer than the cis equatorial pair (2.34, 2.36 A), with the shorter Ru--P(eq) trans to the longer Ru-S. The P-Ru-P angles in each facial set (91 to 100 °, Table 5) are similar to those found in [Ru2C13(PMe2Ph)6] + (Laing & Pope, 1976) and [Ru(OECMe)(PMe2Ph)4] + (Ashworth, Nolte & Singleton, 1976). The pair of axial phosphines bend toward the (SECH) group, P(1)-Ru-P(2) 167 °, to relieve the compression strains between them and the equatorial pair of phosphines.…”

“…1). It was first found in [RUEC13(PMe2Ph)6] + (Laing & Pope, 1976) that for three facially arranged PMe2Ph ligands, one Ru-P-C(Me) angle in each ligand systematically exceeds 120 °, that the P-C bonds to these methyl groups are approximately parallel to each other and perpendicular to the plane of the three P atoms, and that the Me... Me separations are between 3.5 and 3.8 A. The same result was observed in the purple isomer (II) (Ashworth, Singleton & Laing, 1976a) and [RuH(C4H6)(PMe2Ph)3] + (Ashworth, Singleton & Laing, 1976b), and has been used to explain the reactivity of the parent compound [RuH(PMe2Ph)5] + (Ashworth, Nolte, Singleton & Laing, 1977).…”

A Diruthenium Complex of an N‐Pyridyl‐o‐aminophenol Derivative: A Route to Mixed Valency

“…The Ru(1)−Cl(1) bond length is 2.347(2) Å, whereas the Ru(2)−Cl(4) and Ru(2)−Cl(5) bond lengths are 2.311(2) and 2.329(2) Å, respectively, which are consistent with a ruthenium(III) state. For comparison, the terminal and bridging Ru−Cl bond lengths of diruthenium(III,III), diruthenium(II,II), diruthenium(II,III) and 1⋅ MeOH are listed in Scheme . The average Ru−Cl b (b=bridging) bond lengths are significantly different for the [Ru III (μ‐Cl) 3 Ru III ], [Ru II (μ‐Cl) 3 Ru III ] and [Ru II (μ‐Cl) 3 Ru II ] units.…”

Preparation and crystal structure of [Ru2(μ-Cl)3(P(CH2OH)3)6]Cl

“…1) contains binuclear cations [Ru 2 (μ Cl) 3 (P(CH 2 OH) 3 ) 6 ] + and Clanions. The binuclear complex has a {P 3 Ru(μ Cl) 3 RuP 3 } + core built of two confacial octahedra with a nonbonding Ru⋅⋅⋅Ru distance of 3.350 Å, typical of this class of Ru(II) complexes [17][18][19][20][21][22][23][24][25][26][27]. Each Ru atom has an octahedral environment and is coordinated with three chlorine atoms and three phosphorous atoms of the THP ligands.…”

“…The valence angles Cl-Ru-Cl and P-Ru-P are close to 80° and 95°-97°, respectively (Table 3). This geometry is unexceptional for the {Ru 2 (μ Cl) 3 RuP 6 } + core [17][18][19][20][21][22][23][24][25][26][27]. The CH 2 OH groups of all THP molecules in the crystal structure of I are disordered over three posi tions.…”
