A reaction of the triple cubane-type organometallic polyoxomolybdate cluster, [(Cp * Rh)4Mo4O16] · 2H2O (1 · 2H2O), with 1,2-benzenedithiol gives a 1,2-benzenedithiolate-bridged dinuclear complex, [(Cp * Rh)2(μ(S)-1,2-C6H4S2-S,S′)2] (2), and another dinuclear complex, [(Cp * Rh)2(μ(S)-1,2-C6H4S2-S,S′)(μ(S)-1,2-C6H4S(SO2)-S,S′)] (3), both of which are characterized by the single-crystal X-ray diffraction method. The former complex, 2, is also obtained from a reaction of [(Cp * RhCl)2(μ-Cl)2] with 1,2-benzenedithiol in the presence of NaOCH3, and the latter, 3, from oxygenation of 2 with t-BuOOH. The 1H NMR study in CD2Cl2 indicates that complex 2 changes gradually to a coordinatively unsaturated mononuclear complex, [Cp * Rh(1,2-C6H4S2-S,S′)] (4). An analogous mononuclear iridium(III) complex, [Cp * Ir(1,2-C6H4S2-S,S′)] (5), is also prepared and characterized by X-ray structural analysis. © 1997 Elsevier Science S.A.

A new phosphine ligand, 8-(dimethylphosphino)quinoline (Me₂Pqn), and its palladium(I or II) complexes, [PdX₂(Me₂Pqn)] (X = Cl (1a), Br (1b), and I (1c)), [Pd(Me₂Pqn)₂](BF₄)₂ (2b), and [Pd₂Cl₂(Me₂Pqn)₂] (3), have been prepared and characterized. The structures of 2b and 3 have been determined by X-ray analysis. The crystal data and final R values are: for 2b, FW = 658.42, monoclinic, P2₁/n, a = 17.453(2), b = 10.453(2), c = 14.928(2) Å, β = 105.63(1)°, V = 2622.8(5) Å³, D_x = 1.667 Mg m⁻³, and Z = 4, R = 0.071 for 3908 reflections (|F_o| ≥ 3σ(|F_o|)); for 3, MW = 662.64, monoclinic, P2₁/n, a = 16.429(1), b = 12.191(1), c = 12.821(1) Å, β = 92.673(8)°, V = 2565.1(4) Å³, D_x = 1.714 Mg m⁻³, and Z = 4, R = 0.056 for 5136 reflections (|F_o| ≥ 3σ(|F_o|)). In 2b the square coordination plane formed by two long Pd–N (2.138(9) and 2.135(8) Å) and two Pd–P bonds (2.243(3) and 2.237(3) Å) is slightly distorted towards tetrahedral geometry, the dihedral angle between the two chelate planes formed by the Pd, P, and N atoms being 10.3(2)°. 3 is a dinuclear complex with a Pd–Pd bond (2.542(1) Å), Me₂Pqn chelates to one Pd(I) center, and the N donor atom occupies the trans position to the Pd–Pd bond. The dihedral angle between the two coordination planes linked by the Pd–Pd bond is nearly a right angle, 82.13(6)°.
