Abstract The σ-ferrocenyl complex CpW (NO)2Fc (1) was prepared from CpW (NO)2Cl and ferrocenyl lithium, and oxidized by air in CH2Cl2 solution to give CpWO2Fc (2). An X-ray crystal structure analysis of 1 indicated the presence of two almost linear nitrosyl groups (with W -N -O angles of 173.0(9) and 175.4(7)°). The W -C (ferrocenyl) bond length is 2.164(10) Å.

The title compound (H2tpsac) was synthesized from 6-bromosaccharin and 3,3’’-bis(bromomethyl)- m-terphenyl. The ability of tpsac to serve as a tetradentate bis-bridging ligand was demonstrated by the formation of the dinuclear ruthenium(I,I) complexes [Ru2(CO)5(μ,μ-tpsac)]2, [Ru2(CO)4(μ,μ-tpsac)]n, [Ru2(CO)4(PPh3)2(μ,μ-tpsac)], and [Ru2(CO)5(PPh3)(μ,μ-tpsac)]. An X-ray crystal structure analysis of [Ru2(CO)4(PPh3)2(μ,μ-tpsac)] showed the head-to-tail (or 1,1) arrangement of the two saccharinate coordination sites.

Abstract Reaction of the tetrahydrofuran-stabilized 16-electron complex fragment [Cp*Re(CO)2] with dimethyl disulfide, MeSSMe, leads to the diamagnetic title compound, Cp*Re(CO)(SMe)2 , which was characterized by mass, IR and NMR spectra and by an X-ray crystal structure analysis**. The two methylsulfido ligands are bent (angles Re-S-CH3 114.1(3)°) and turned away from the Cp* ring. The Re - S-bond distances are 227.0(2) pm.

Use of mixed-ligand (bromide and thiocyanate ions) coordination with nickel has led to the crystallization of the title compound, (C24H20As)2[Ni(NCS)2Br2]. X-ray crystal structure analysis reveals that the asymmetric unit contains one (C6H5)4As+ cation and one half [Ni(NCS)2Br2]2− anion, the latter lying on a crystallographic twofold axis.
