Notes: Abstract The reaction between Ru5(μ5-C2PPh2)(μ-PPh2)(CO)13 and Au(C2Ph)(PPh3) afforded AuRu5(μ5-C2PPh2)(μ-C2Ph)(μ-PPh2)(CO)13 (PPh3), in which the Ru5 cluster has a scorpion geometry; the Au(PPh3) group bridges one of the Ru-Ru bonds of the Ru3 triangle, while the C2Ph group bridges one of the tail Ru-Ru vectors.

Notes: Abstract The reactions between Ru5(μ 5-C2PPh2)(gm-PPh2(CO)13 (1) and cyclopentadienes afforded the hexanuclear clusters Ru6(μ 6-C)(μ 3-PPh2)2(CO)10(η-C5 R 5) [R 5 = H5 (2), H4Me (3), Me5 (4)] which contain an encapsulated carbide and a face-cappingμ 3-CH group, formed by cleavage of CC and CP bonds of the C2PPh2 moiety in1. In the reaction with cyclopentadiene, the unusual ligand C13H12O, formed by combination of C2, CO and two molecules of C5H6 (or one molecule of dicyclopentadien), was characterized in the complex Ru5(μ 4-PPh) (μ 4-C13H12O)(μ-PPh2(CO)11(η-C5H5) (5). In the reaction with pentamethylcyclopentadiene, the vinylidene complex Ru5(μ 3-CCHPh)(μ 4-PPh)(μ 4-PPh) (μ-PPh2)(CO)9(η-C5Me5) (6) was also formed.

Notes: Abstract The reaction between Ru3(μ3-ν2-PhC2C=CPh)(μ-dppm)(CO)8 and Co2(CO)8 afforded dark red Co2Ru3(μ4-C2Ph)(μ3-C2Ph)(μ-dppm)(μ-CO)2(CO)9, shown by an X-ray structure determination to contain a strongly twisted Co2Ru3 bow-tie cluster (central Co), to which two PhC2 units derived from cleavage of the original diyne are attached. One a these is strongly interacting with four metal atoms, the other being attached in the familiar ν1,2ν2-mode. The dppm ligand remains bridging two of the Ru atoms.

Notes: Abstract Addition of aqueous HCl to Ru5(μ 3-C=CH2)(μ-SMe)2(μ-PPh2)2(CO)10 afforded the structurally characterized carbyne complex Ru5(μ 3-SMe)(μ 3-CMe)(μ-Cl)(μ-SMe)(μ-PPh2)2(CO)9, formed by addition of H to the vinylidene ligand; a Cl atom bridges an Ru–Ru bond.

Notes: Reduction of [Yb(Odpp)3(THF)2(HOdpp = 2,6-diphenylphenol; THF = tetrahydrofuran) with ytterbium powder and mercury metal yields [Yb(Odpp)2(THF)3] (1) which on crystallization from DME gives [Yb(Odpp)2(DME)2] (2) (DME = 1,2-dimethoxyethane). Crystallization of the reactant [Yb(Odpp)3(THF)2] from DME yields [Yb(Odpp)3(DME)]. (DME)0,5 (3) and of [Nd(Odpp)3(THF)2] from DME/THF the analogous [Nd(Odpp)3(DME)]. (THF) (4). The X-ray crystal structure of 1 reveals distorted trigonal bipyramidal five-coordinate ytterbium with axial Odpp ligands [O-Yb-O 164.6(3)˚], and unsymmetrically distributed equatorial THF ligands [O-Yb-O 137.5(3), 138.8(3), 83.7(4)°] owing to two close H(Ph)...Yb approaches (3.1-3.2 Å). In 2, there is trigonal prismatic six-coordination with an Odpp ligand on each triangular face and DME ligands bridging the triangular faces. Both 3 and 4 have distorted square planar five-coordination for the lanthanoid metals with an apical Odpp ligand and cisoid Odpp ligands and a chelating DME in the square plane.

Notes: Triphenyltin(IV) compounds of p-ethoxybenzoic acid and acetylsalicylic acid contain molecular units with Sn-O bonds and distorted tetrahedral tin centers. The phthalic acid derivative contains two four-coordinate tin atoms between which the phthalic acid unit effectively forms a bridge. The salicylaldehydato compound is polymeric with trigonal bipyramidal tin centers in which the phenyl groups take equatorial positions. The polymerization occurs via the aldehyde oxygen atom bonding to a neighboring tin atom. © 1998 John Wiley & Sons, Ltd.
