The reaction of arsenic, MgSO4 and S2Cl2 in acetonitrile yielded the title compound along with 4,5- dichloro-1 ,2,3-dithiazolium chloride, [C2NS2Cl2]Cl (which was formed from the solvent and S2Cl2). The crystal strucutre of [Mg(NCCH3)6][As4Cl14] was determined by X-ray diffraction. It is triclinic, space group P1¯, Z = 2, R = 0.049. The Mg2+ ion is coordinated by six acetonitrile ligands. The anions consist of AsCl4- and AsCl3 units which are associated to chains along the a axis by As ··· Cl contacts. Each As atom has distorted octahedral coordination.

The title compound was obtained by the reaction of PPh4Br, Sb2Se3, and bromine in dichloromethane. Its crystal structure was determined by X-ray diffraction. Crystal data: a = 1249.1(2), b = 1307.8(2), c = 2152.3(4) pm, α = 102.93(2), β = 100.83(2), γ = 100.42(2)°, Z = 2, triclinic, space group P1̄. (PPh4)4Sb8Br28 is isotypic with (PPh4)4Sb8I28. The Sb8Br284- ion can be taken as the association product of eight SbBr3 molecules with four Br− ions. Each Sb atom has a distorted octahedral coordination with three shorter (252 to 274 pm) and three longer (300 to 353 pm) Sb-Br bonds. The octahedra share common edges in two parallel rows of four octahedra each. The arrangement of the 28 bromine atoms corresponds to a section of a closest packing of spheres.

The title compound is prepared from naphthazarine (5,8-dihydroxy-1,4-naphthoquinone) and tetraphenylstibonium ethoxide (molar ratio 1:2) in dioxane as a solvent. X-ray analysis shows the naphthazarine dianion to act as a bifunctional chelating ligand in which two 2,2′-connected 1,3-diketonato groups are fixed in a coplanar position by two cis-ethenediyl bridges. The interaction of the naphthazarine dianion with the tetraphenylstibonium ions is an intermediate between ionic and covalent bonding. Consequently the antimony ions have strongly distorted octahedral coordination spheres (Sb–O 225,5(4) pm, Sb–Ce 215,9(6) pm, Sb–Ca 214,8(5) pm; O-Sb-O 75,9(1)°, Ce– Sb– Ce 103,8(2)°, Ca–Sb–Ca 166,0(2)°). The chelate rings are folded at the O/O axes (angles of fold 20-36°), the two antimony centers being arranged in trans-positions relative to the plane of the naphthazarine dianion.

Two new saccharinato-silver(I) (sac) complexes, [Ag(sac)(ampy)] (1), and [Ag2(sac)2(μ-aepy)2] (2), [ampy = 2-(aminomethyl)pyridine, aepy = 2-(2-aminoethyl)pyridine], have been prepared and characterized by elemental analysis, IR spectroscopy, thermal analysis and single crystal X-ray diffraction. Complexes 1 and 2 crystallize in the monoclinic space group P21/c and triclinic space group P1̄, respectively. The silver(I) ions in both complexes 1 and 2 exhibit a distorted T-shaped AgN3 coordination geometry. 1 consists of individual molecules connected into chains by N-H···O hydrogen bonds. There are two crystallographically distinct dimers in the unit cell of 2 and in each dimer, the aepy ligands act as a bridge between two silver(I) centers, resulting in short argentophilic contacts [Ag1···Ag1 = 3.0199(4) Å and Ag2···Ag2 = 2.9894(4) Å ]. Symmetry equivalent dimers of 2 are connected by N-H···O hydrogen bonds into chains, which are further linked by aromatic π(py)···π(py) stacking interactions into sheets.

Both ambidentate ligands NCS and NCSe are bonded via the N atom. Using the molecular parameters of the X-ray determinations the low temperature (10 K) IR and Raman spectra of the (n-Bu4N) salts have been assigned by normal coordinate analysis based on a modified valence force field. The valence force constants fd(ReN) are 1,78(NCS) and 1,79(NCSe) mdyn/ Å.

The title compound, [Co(C18H37N2)2(NCS)4], consists of a cobalt(II) ion positioned on the origin of the triclinic unit cell. It is coordinated by the N atoms of two trans-oriented 1-dodecyl-4-aza-1-azoniabicyclo[2.2.2]octane (DABCO+) cations, which carry n-dodecyl chains at the non-coordinating N atoms. The distorted octahedral coordination environment of the CoII ion is completed through four N atoms of isothiocyanate ions, which are arranged within the equatorial plane. Non-classical hydrogen bonding of the types C—H...N and C—H...S between the filamentous molecules lead to the formation of layers parallel to (001).
