Bis[2,2'-(2-amino-ethyl-imino)-di(ethyl-ammonium)] di-μ-sulfido-bis[disulfido-stannate(IV)].

ABSTRACT: The asymmetric unit of the title compound, (C(6)H(20)N(4))(2)[Sn(2)S(6)], comprises half of a [Sn(2)S(6)](4-) anion and a diprotonated tris-(2-amino-eth-yl)amine cation. The anion lies on an inversion center, while the atoms of the cation occupy general positions. An intra-molecular N-H⋯N hydrogen bond is observed in the cation. In the crystal, strong N-H⋯S hydrogen bonding between the terminal sulfur atoms of the anion and the protonated amine N atoms of the cations result in a three-dimensional network.

catena-Poly[[tetra-kis-(hexa-methyl-phospho-ramide-κO)bis-(nitrato-κO,O')cerium(III)] [silver(I)-di-μ-sulfido-tungstate(VI)-di-μ-sulfido]].

Project description:Hexa-methyl-phospho-ramide (hmp), tetra-thio-tungstate, silver sulfide and cerium nitrate were self-assembled to form a one-dimensional anionic [Ag(4)W(4)S(16)](n) (4n-) chain in the title compound, {[Ce(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n). The asymmetric unit contains four crystallographically independent [Ce(hmp)(4)(NO(3))(2)](+) cations, which leads to a one-dimensional polymeric anionic chain having a tetra-valent [W(4)S(16)Ag(4)] repeat unit. Each central Ce atom is coordinated by eight O atoms from two chelating nitrate and four hmp ligands, which gives rise to a distorted square-anti-prismatic structure. The polymeric chain with average W-Ag-W and Ag-W-Ag bond angles of 163.75 and 151.84°, respectively, presents a distorted linear configuration. The title complex with a non-centrosymmetric structure, is analogous to the Yb, Y, Eu, Nd, La and Dy isomorphs, which exhibit centrosymmetric structures.

Project description:Hexamethyl-phospho-ramide (hmp), tetra-thio-molybdate, silver sulfide and dysprosium nitrate were self-assembled to form an anionic [AgMoS(4)](n) (n-) chain in the title complex, {[Dy(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgMoS(4)]}(n). The central Dy atom in the cation is coordinated by eight O atoms from two nitrate and four hmp ligands, resulting in a distorted square-anti-prismatic environment. Together with the two nitrate ligands, the cation is monovalent, which leads to the anionic chain having an [AgMoS(4)] repeat unit.

The title complex is isostructural with the W analogue.

Project description:In the cation of the title compound, {[Y(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgMoS(4)]}(n), the Y atom is coordinated by eight O atoms from two chelating nitrate groups and four hexa-methyl-phospho-ramide (hmp) ligands, which gives rise to a distorted square-anti-prismatic environment. Together with the two nitrate ligands, the overall charge for the complex cation is +1, which leads to the anionic chain having a monovalent repeat unit. The polymeric anionic chain, with Mo-Ag-Mo and Ag-Mo-Ag angles of 161.916 (13) and 153.915 (13)°, respectively, presents a distorted linear configuration.

The structure is isotypic with the corresponding W, Yb, Eu, Nd, La and Dy complexes.

The central Dy atom in the cation is coordinated by eight O atoms from two didentate nitrate and four hmp ligands, giving rise to a distorted square anti-prismatic structure. Together with the two nitrate ligands, the cation is univalent, which leads to the anionic chain having a [WS(4)Ag] repeat unit. The polymeric anionic chain, with W-Ag-W and Ag-W-Ag angles 161.16 (2) and 153.606 (11)°, respectively, presents a distorted linear configuration. The title compound is isotypic with other rare earth complexes.

Di-μ(1,1)-azido-bis-[(2-{1-[2-(isopropyl-amino)ethyl-imino]eth-yl}phenolato)copper(II)].

Project description:In the centrosymmetric binuclear title complex, [Cu(2)(C(13)H(19)N(2)O)(2)(N(3))(2)], the Cu(II) atom adopts an elongated CuON(4) square-based pyramidal coordination geometry, arising from the N,N',O-tridentate ligand and two bridging end-on azide anions. The O atom is in the basal plane, one of the azide N atoms is in the apical site and the Cu⋯Cu separation is 3.2365 (3) Å. A pair of intra-molecular N-H⋯O hydrogen bonds helps to establish the mol-ecular conformation.
