Poly[tetra-?-cyanido-dipyridine-cadmium(II)zinc(II)].

ABSTRACT: In the title coordination polymer, [CdZn(CN)(4)(C(5)H(5)N)(2)](n), the Zn(II) atom (site symmetry 222) adopts a distorted ZnC(4) tetra-hedral geometry, being coordinated by four crystallographically equivalent cyanide ions. The cyanide ion bridges to a Cd(II) centre via its N atom. The Cd atom (site symmetry 2/m) coordination is a distorted CdN(6) octa-hedron, arising from four cyanide N atoms and two pyridine N atoms. The complete pyridine mol-ecule is generated by m symmetry, with the N atom and one C atom lying on the reflecting plane. In the crystal, the bridging cyanide ions result in a three-dimensional network.

catena-Poly[[dipyridine-cadmium(II)]-?-5-amino-2,4,6-triiodo-isophthalato].

Project description:The hydro-thermal reaction of cadmium(II) nitrate with 5-amino-2,4,6-triiodo-isophthalic acid and pyridine in DMF solution leads to the formation of the title compound, [Cd(C(8)H(2)I(3)NO(4))(C(5)H(5)N)(2)](n). The structure contains a four-coordinate Cd(2+ )ion in a distorted tetra-hedral geometry, which lies on a crystallographic twofold rotation axis. The Cd(2+ )ion is bonded to two N atoms from two pyridine ligands and two carboxyl-ate O atoms from two 5-amino-2,4,6-triiodo-isophthalate anions. The Cd-O distances are 2.429?(5) and 2.305?(5)?Å and the Cd-N distance is 2.236?(8)?Å. The two carboxyl-ate groups of individual 5-amino-2,4,6-triiodo-isophthalate anions act as a bridge to the Cd(2+) atoms. leading to a chain structure along the c axis.

Poly[[tri-μ-cyanido-cyanido(1,4,10,13-tetra-oxa-7,16-diaza-cyclo-octa-deca-ne)barium(II)platinum(II)] hemihydrate].

Project description:The title compound, {[BaPt(CN)(4)(C(12)H(26)N(2)O(4))]·0.5H(2)O}(n), is a two-dimensional coordination polymer in which the sheets are oriented approximately parallel to the (01) set of crystal planes. In the crystal structure, disordered water mol-ecules (half occupancy) connect the sheets into a three-dimensional network via inter-molecular O-H⋯O hydrogen bonds. An N-H⋯N inter-action is also present. The shortest Pt⋯Pt contacts are 7.5969 (4) Å by an inversion relationship and 7.6781 (4) Å by translation along the a axis.

Crystal structure of poly[[di-aqua-tetra-μ2-cyanido-iron(II)platinum(II)] acetone disolvate].

Project description:In the title polymeric complex, {[FePt(CN)4(H2O)2]·2C3H6O} n , the FeII cation has an octa-hedral [FeN4O2] geometry being coordinated by two water mol-ecules and four cyanide anions. The Pt cation is located on an inversion centre and has a square-planar coordination environment formed by four cyanide groups. The tetra-cyano-platinate anions bridge the FeII cations to form infinite two-dimensional layers that propagate in the bc plane. Two guest mol-ecules of acetone per FeII are located between the layers. These guest acetone mol-ecules inter-act with the coordinated water mol-ecules by O-H⋯O hydrogen bonds.

Poly[tetra-aqua-di-μ(4)-malonato-barium(II)cadmium(II)].

Project description:In the title complex, [BaCd(C(3)H(2)O(4))(2)(H(2)O)(4)](n), the Ba(II) atoms, located on crystallographic twofold axes, adopt slightly distorted square-anti-prismatic coordination geometries, while the Cd(II) atoms, which lie on crystallographic centres of symmetry, have a distorted octa-hedral coordination. Each malonate dianion binds two different Cd(II) atoms and two different Ba(II) atoms. This connectivity generates alternating layers along [100] in the structure, with one type containing Cd(II) cations and malonate dianions, while the other is primarily composed of Ba(II) ions and coordinated water mol-ecules. The water mol-ecules also participate in extensive O-H⋯O hydrogen bonding.

Project description:In the crystal structure of the title compound, [Cd(C(10)H(8)N(2))(H(2)O)(4)](C(4)H(2)O(4))·4H(2)O, the Cd(II) atom, on an inversion centre, is six-coordinated by four O atoms from four water mol-ecules and two N atoms from 4,4'-bpy mol-ecules in a distorted octa-hedral coordination geometry. Weak C-H⋯O inter-actions between uncoordinated carboxyl-ate O atoms of fumaric acid and water mol-ecules contribute to the crystal packing stability.

Poly[diaqua-tetra-μ-seleno-cyanato-cadmium(II)dipotassium(I)].

Project description:In the title compound, [CdK(2)(NCSe)(4)(H(2)O)(2)](n), the cadmium(II) cation is situated on a twofold rotation axis and is coordinated in a slightly distorted tetra-hedral geometry by two symmetry-related μ-1,1,1,3 and two-symmetry related μ-1,1,3,3 bridging seleno-cyanate anions, all of which are Se bonded. These bridging seleno-cyanate anions are further coordinated to two symmetry-related potassium ions. Each of the potassium ions is coordinated by one terminally bonded water mol-ecule and six seleno-cyanate anions, two of which are crystallographically independent. The asymmetric unit consists of one cadmium and one potassium cation, two bridging seleno-cyanate anions and one water mol-ecule. The polymeric subunits are further connected via the seleno-cyanate anions into a three-dimensional coordination network. In this coordination network, intramolecular hydrogen bonds between neighbouring water molecules can be found.

Poly[bis[3,10-bis(2-hydroxyethyl)-1,3,5,8,10,12-hexa-azacyclo-tetra-deca-ne]tetra-μ-cyanido-tetracyanidodicopper(II)molybdenum(IV)] tetra-hydrate].

Project description:In the title complex, {[Cu(2)Mo(CN)(8)(C(12)H(30)N(6)O(2))(2)]·4H(2)O}(n), the polyhedron around Mo has site symmetry with a distorted square-antiprismatic shape, while the Cu atom (2 symmetry) is in a distorted axially elongated octa-hedral coordination environment. The uncoordinated water molecule is disordered over three sites with occupancies of 0.445 (7), 0.340 (7) and 0.215 (7). Mo and Cu atoms acting as basic components are connected by an Mo-CN-Cu-NC-Mo- linkage to form a distorted diamond-like network. Additional hydrogen bonding between the N-H groups and the water molecules stabilizes this arrangement.
