The asymmetric unit of the title compound, [Mo(2)(η(5)-C(5)H(5))(2)(C(22)H(29)P)(2)(CO)(4)]·2C(4)H(8)O, contains two half-mol-ecules of the organometallic species and two solvent mol-ecules. Both organometallic mol-ecules are completed by crystallographic inversion symmetry, yielding dimeric units with Mo-Mo single-bond lengths of 3.2703 (6) and 3.2548 (6) Å. Each Mo atom is also coordinated by an η(5)-cyclo-pentdienyl ligand, two carbonyl ligands, and a (dec-9-en-1-yl)diphenyl-phosphine ligand.

The title compound, [Fe(CHO)(HO)][FeGa(CHOSi)Cl(CO)]·4CHO, consists of an iron(II) cation octa-hedrally coordinated by two water mol-ecules () with four tetra-hydro-furans (THF) at equatorial sites. Two additional THF mol-ecules are hydrogen bonded to each of the water mol-ecules. The dianion of the title compound is an organometallic butterfly complex with a dimethyl siloxane core and two iron-gallium fragments.

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.
