Magnesium metal is an ideal rechargeable battery anode material because of its high volumetric energy density, high negative reduction potential and natural abundance. Coupling Mg with high capacity, low-cost cathode materials such as electrophilic sulphur is only possible with a non-nucleophilic electrolyte. Here we show how the crystallization of the(More)

The asymmetric unit of the title compound, [Nd(2)(C(6)H(5)COO)(5)Cl(C(4)H(8)O(2))]·2.5C(4)H(8)O(2), consists of two Nd(III) ions bridged by one Cl(-) ion, five benzoate ions and one coordinating 1,4-dioxane mol-ecule. One Nd(III) ion is nine-coordinate, with a very distorted monocapped square-anti-prismatic geometry. It is coordinated by two chelating(More)
The title compound, {[K(2)(C(12)H(6)N(2)O(4))(H(2)O)(2)]·2H(2)O}(n), forms a three-dimensional coordination polymer in the solid state. The asymmetric unit consists of one K(+) ion, half of a 2,2'-bipyridyl-5,5'-dicarboxyl-ate ligand, one coordinated water mol-ecule and one solvent water mol-ecule. The K(+) ion is 7-coordinated by the oxygen atoms of two(More)
The structure of the mononuclear title complex, [{(H3CS)2C=NC  N}2CoCl2], consists of a Co(II) atom coordinated in a distorted tetra-hedral manner by two Cl(-) ligands and the terminal N atoms of two dimethyl N-cyano-dithio-imino-carbonate ligands. The two organic ligands are almost coplanar, with a dihedral angle of 5.99 (6)° between their least-squares(More)
The synthesis of the title hydrated complex salt, [Co(C6H14N2)3]Cl3·H2O, from racemic trans-1,2-di-amino-cyclo-hexane and [CoCl(NH3)5]Cl2 and its structural characterization are presented in this paper. The product was synthesized in the inter-est of understanding the hydrogen-bonding patterns of coordination complexes. Previous characterizations of the(More)
The Cu(II) atom in the title compound, [CuCl2(C14H21F3N4)], adopts a coordination geometry that is between distorted square-based pyramidal and very Jahn-Teller-elongated octa-hedral. It is coordinated by three N atoms from the bis-(2-amino-eth-yl)(2-{[4-(tri-fluoro-meth-yl)benzyl-idene]amino}-eth-yl)amine and two chloride ligands. The two(More)
In the asymmetric unit of the title compound, [CuBr(C18H18N4)]Br, there are three crystallographically independent cations. One of the cations exhibits positional disorder of the pyridin-2-yl-methyl groups over two sets of sites with refined occupancies of 0.672 (8) and 0.328 (8). The outer-sphere bromine counter-ion is severely disordered over multiple(More)
Two porphyrin complexes were studied to determine the effects of protonation on ring deformation within the porphyrin. The porphyrin 7,8,17,18-tetra-bromo-5,10,15,20-tetra-phenyl-porphyrin, C44H26Br4N4, was selected because the neutral species is readily doubly protonated to yield a dication, which was crystallized here with perchlorate counter-ions as a(More)
The almost planar (r.m.s. deviation = 0.055 Å) title compound, (MeS)C(O)NHC(O)NH2, was formed during an attempted crystallization of dimethyl cyano-carbonimidodi-thio-ate with CrO2Cl2; an unexpected redox reaction converted the cyano-carbonimido moiety to a urea group and removed one methyl-thiol group. In the crystal, hydrogen-bonding inter-actions from(More)
