The X-ray structure determination was now successful including all hydrogen positions.P21/c, Z = 2, a = 6.372(1) Å, b = 10.940(2) Å, c = 5.749(2) Å, β = 101.94(2)° N(F2o ≥ 3σF2o) = 809, N(Var.) = 69, R/RW = 0.011/0.012The compound CaZn2(OH)6 · 2H2O contains Zn2+ in tetrahedral coordination by OH- and Ca2+ in octahedral coordination by four OH- and two H2O. The tetrahedra around Zn2+ form corner sharing chains, three-dimensionally linked by isolated polyhedra around Ca2+. Weak hydrogen bridge bonds result between H2O as donor and OH-.

    Description / Table of Contents: Crystal Structure of SrZn(OH)4 · H2OColorless crystals of SrZn(OH)4 · H2O are obtained by electrochemical oxidation of Zn in a zinc/iron pair in an aqueous ammonia solution saturated with strontium hydroxide. The X-ray crystal structure determination was now successful including all hydrogen positions: P1, Z = 2, a = 6.244(1) Å, b = 6.3000(8) Å, c = 7.701(1) Å, α = 90.59(1)°, β = 112.56(2)°, γ = 108.66(2)°, N(F2o ≥ 3σF2o) = 1967, N(Var.) = 84, R/Rw = 0.020/0.024.In SrZn(OH)4 · H2O Zn2+ is tetrahedrally coordinated by four OH- -ions while Sr2+ has 6 OH- and one H2O as neighbours. The polyhedra around Sr2+ are connected to chains which are linked three-dimensionally by isolated tetrahedra [Zn(OH)4]. Hydrogen bonds between H2O as donor and OH- are characterized by raman spectroscopy.

    Description / Table of Contents: Synthesis and Crystal Structure of BaZn2(OH)6 · 5 H2OThe electrochemical corrosion of zinc in a zinc/iron pair leads in an ammonia containing solution of barium hydroxide at room temperature to colourless platelets of crystals of BaZn2(OH)6 · 5H2O. The X-ray structure determination on these crystals was successful including all hydrogen positions: P21/c, Z = 4, a = 6.181(2) Å, b = 16.126(3) Å, c = 11.121(2) Å, β = 99.69(2)° Z(Fo2 ≥ 3 σ Fo2) = 3281, Z(Var.) = 178, R/Rw = 0.020/0.021 BaZn2(OH)6 · 5 H2O crystallizes in a layer structure. The layers contain Zn2+ in tetrahedral coordination by OH- and Ba2+ in an onefold capped tetragonal antiprism of 6 H2O and 3 OH-. Hydrogen bridge bonds of a further H2O molecule between the layers to OH- and H2O connect these three-dimensionally.

    Notes: [Zr2Cl4(NPMe3)4(HNPMe3)] · CH3CN, a Phosphorane Iminato Complex with Zr=N Double BondsThe title compound has been prepared from a molten mixture of ZrCl4 with Me3SiNPMe3 in the presence of potassium fluoride and subsequent extraction with acetonitrile. According to the crystal structure determination the zirconium atoms are linked by three μ2-N atoms of two NPMe3- groups and by the HNPMe3 molecule. Two terminal bounded chlorine atoms and a terminally coordinated NPMe3- ligand complete the distorted octahedral surrounding of the zirconium atoms thus forming an edge sharing double octahedron. The ZrN bond lengths of the terminal NPMe3- groups of 194.6 pm correspond with double bonds.
