[{Ru(CO)3Cl2}2] reacts with the in situ prepared reagent Li2[Fe(CO)3(PBut2)2] to give the new heterobinuclear complex [FeRu(CO)5(μ-PBut2)2] (1). Crystals of 1 are isomorphous to those of the known compound [Fe2(CO)5(μ-PBut2)2] (2) and crystallize in the triclinic space group P1̄ with a = 867,5(1), b = 1181,0(2), c = 1373,1(2) pm; α = 76,64(1), β = 79,72(1) and γ = 76,48(1)°. A double bond between the two metal atoms concluded for 2 from the results of EHMO calculations is also proposed for 1 (Fe=Ru: 259,8(1) pm).

The Difference

Abstract β-VCl2(N3S2) was obtained by sublimation. It represents a new modification compared to the known α-VCl2(N3S2) which can be obtained from solution. Its crystal structure was determined by X-ray diffraction (864 observed reflexions, R = 0.034). Crystal data: triclinic, space group P1̄, Z = 2, a = 570.0, b = 779.9, c = 735.3 pm , α = 90.85°, β = 108.26°, y = 98.77°. Both modifications consist of polymer chains in which the vanadium atoms are linked alternatively by chloro and nitrogen bridges. The packing of the chains is rather similar, the only difference being that in β-VCl2(N3S2) the chains are rotated by 11° as compared to the orientation in α-VCl2(N3S2). The difference of the two modifications also shows up in the slightly different IR spectra. By reduction of VCl2(N3S2), dissolved in CH2Cl2/pyridine, with H2S, zinc or PPh3, the cyclothiazeno complex [VCl(N3S2)(pyridine)2]2·2 CH2Cl2 was obtained. It crystallizes in the monoclinic space group P 21/c, Z = 4, a = 1010.4, b = 917.3, c = 1967.8 pm, β = 103.03° (structure determination with 649 observed reflexions. R = 0.081). In this vanadium(IV) compound the metal atoms are part of planar VN3S2 rings as found in the VCl2(N3S2) modifications. The two vanadium atoms of the centrosymmetrical dimer are linked via one nitrogen atom of each of the VN3S2 rings; the resulting V2N2 ring is coplanar with the two VN3S2 rings.

AbstractThe reaction of [Mn(CO)5]- with the cluster cation [(Ph3PAu)8]2+ in thf yields the heterometallic cluster [(Ph3PAu)4 [AuMn(CO)5]2 (1) as the main product besides small amounts of (Ph3PAu)3Mn(CO)4. The former crystallizes as 1-thf in form of red blocks in the triclinic space group P1 with a = 1391,0( 1), b = 1426.7( 1), c = 2308.3(2) pm, α = 92.87(1), β = 97.54( 1), γ = 96.43(1)° and Z = 2. The inner Au6 skeleton of the almost centrosymmetrical cluster consists of two Au4 tetrahedra sharing one edge. Two gold atoms bind a Mn(CO)5 fragment, whereas to the other four gold atoms phosphine ligands are coordinated. The Au-Au distances range from 263.2(1) to 281.9(1) pm, and the Au-Mn distances are 256.6(3) and 256.9(2) pm. By the reaction of [(Ph3PAu)8]2+ with [Re2(CO)9]2- the cluster (Ph3PAu)3Re(CO)4 (2) is obtained in low yield besides the homometallic cluster [(AuPPh3)7]+ as the main product. 2 crystallizes from toluene as 2 C7H8 in the form of yellow blocks with the orthorhombic space group Pna21, and a = 1758.7(3), b = 1648.7(5), c = 2049.3(5) pm. The four metal atoms form a planar lozenge with the Re atom in equatorial position. The Re-Au distances range from 271.2(1) to 273.7(1) pm, and the Au-Au distances are 278.2(1) and 278.4(1) pm
