The title compound, [Au(2)Cl(2)(C(28)H(30)N(2)P(2))]·2C(4)H(8)O, was synthesized from a bidentate phosphine ligand complexed to two linear gold(I) chloride moieties. The Au(I) atom is in an almost linear coordination with a P-Au-Cl angle of 179.22 (4)°. The complex molecules reside on a twofold rotation axis.

Tetra-kis(μ-acetato-κ :')bis-{[1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene-κ ]chromium(II)} tetra-hydro-furan disolvate, [Cr(CHO)(CHN)]·2CHO or [Cr(OAc)(IDipp)]·2CHO (), and tetra-kis-(μ-acetato-κ :')bis-{[1,3-bis-(2,4,6-tri-methyl-phen-yl)imidazol-2-yl-idene-κ ]chromium(II)},{Cr(CHO)(CHN)] or [Cr(OAc)(IMes)] (), were synthesized from anhydrous chromium(II) acetate [Cr(OAc)] and the corresponding NHC (NHC = N-heterocyclic carbene) in toluene as solvent. Both complexes crystallize in the triclinic system, space group . The mol-ecular structures consist of Cr(OAc) paddle-wheels that carry two terminal NHC ligands.

The title compound, [Mo(CHNS)(S)S]S, crystallizes on a general position in the monoclinic space group 2/ (No. 14). The cationic [MoS(SCNBu)] fragments are joined by a mono-sulfide dianion that forms close S⋯S contacts to each of the di-sulfide ligands on the side of the Mo plane opposite the μ ligand.

The neutral organosilicon(IV) complex, (CF)Si(OPO) (OPO = 1-oxopyridin-2-one, CHNO), was synthesized from (CF)Si(OCH) and 2 equiv. of 1-hy-droxy-pyridin-2-one in tetra-hydro-furan (THF). Single crystals grown from the diffusion of -pentane into a THF solution were identified as a THF hemisolvate and an -pentane hemisolvate, (CF)Si(OPO)·0.

The title compound, [Cr(CHO)(CHO)] or [Cr(OAc)(THF)] (OAc is acetate, THF is tetra-hydro-furan), was obtained by recrystallization of anhydrous chromium(II) acetate [Cr(OAc)] from hot tetra-hydro-furan. The centrosymmetric complex forms monoclinic crystals, space group 2/, and consists of two Cr atoms bridged by four acetate ligands. Additionally, each Cr atom is coordinated by a terminal THF ligand, which leads to a square-pyramidal coordination.
