Catena-Poly[[bis-(N-ethyl-ethylene-di-amine-?N,N')copper(II)]-?-cyanido-?N:C-[dicyanido-?C-palladium(II)]-?-cyanido-?C:N].

ABSTRACT: The title compound, [CuPd(CN)(4)(C(4)H(12)N(2))(2)](n), consists of one-dimensional chains. The Cu and Pd atoms are both located on centers of symmetry in an alternating array of [Cu(N-Eten)(2)](2+) (N-Eten = N-ethyl-ethylenediamine) and [Pd(CN)(4)](2-) units. The Pd-C distances of 1.991?(3) and 1.992?(3)?Å are inter-mediate values compared with the analogous Ni(II) and Pt(II) complexes [Akitsu & Einaga (2007 ?). Inorg. Chim. Acta, 360, 497-505]. Due to Jahn-Teller effects, the axial Cu-N bond distance of 2.548?(2)?Å is noticeably longer than the equatorial distances [Cu-NH(2) = 2.007?(2) and Cu-NHC(2)H(5) = 2.050?(2)?Å]. There are interchain hybrogen bonds, with N(-H)?N = 3.099(4)?Å.

Project description:In the title complex, [Cu(I)Cu(II)(CN)3(C4H12N2)2], the Cu(I) and Cu(II) ions and a bridging cyanide group lie on a twofold rotation axis. The Cu(II) ion is in a slightly-distorted square-pyramidal coordination environment, with the N atoms of the two symmetry-related N-ethyl-ethylenedi-amine ligands occupying the basal positions and an N-bonded cyanide group in the apical position. The Cu(I) ion is in a trigonal-planar coordination environment, bonded to the C atom of the bridging cyanide group and to two terminal cyanide groups. In the crystal, N-H?N hydrogen bonds involving two of the symmetry-unique N-H groups of the N-ethyl-ethylenedi-amine ligands and the N atoms of the terminal cyanide ligands link the mol-ecules into strands along [010].

Sodium bis-(ethyl-enedi-amine)-copper(II) tetra-cyanido-cuprate(I).

Project description:The title compound, Na[Cu(en)2][Cu(CN)4], where en represents ethyl-enedi-amine, NH2CH2CH2NH2, crystallizes as a salt with two distinct cations, Na(+) and [Cu(II)en2](2+), and discrete [Cu(I)(CN)4](3-) anions. The anion geometry is tetra-hedral, with angles at the copper atom ranging from 105.0?(1) to 115.4?(1)°. The Cu-C distances are in the range 1.976?(3) to 1.993?(3)?Å. The divalent copper atom is coordinated by four N atoms of the two bidentate en ligands in a slightly distorted square-planar geometry. In the crystal, each sodium ion inter-acts with cyanide N atoms of four different anions, with Na-N distances lying in the narrow range of 2.344?(3) to 2.367?(3)?Å, and an approximately tetra-hedral arrangement around the sodium ions. The inter-acting sodium ions and [Cu(I)(CN)4](3-) anions form a three-dimensional network with channels which contain the [Cu(en)2](2+) cations. One of the chelate rings in the cation shows partial disorder between two different conformations and the C atoms were refined with occupancies in the ratio 0.817?(15):0.183?(15).

Crystal structures of tetra-methyl-ammonium (2,2'-bi-pyridine)-tetra-cyanidoferrate(III) trihydrate and poly[[(2,2'-bi-pyridine-?(2) N,N')di-?2-cyanido-dicyanido(?-ethyl-enedi-amine)(ethyl-enedi-amine-?(2) N,N')-cadmium(II)iron(II)] monohydrate].

Project description:The crystal structures of the building block tetra-methyl-ammonium (2,2'-bi-pyridine-?(2) N,N')tetra-cyanidoferrate(III) trihydrate, [N(CH3)4][Fe(CN)4(C10H8N2)]·3H2O, (I), and a new two-dimensional cyanide-bridged bimetallic coordination polymer, poly[[(2,2'-bi-pyridine-?(2) N,N')di-?2-cyanido-dicyanido(?-ethyl-enedi-amine-?(2) N:N')(ethyl-enedi-amine-?(2) N,N')cadmium(II)iron(II)] monohydrate], [CdFe(CN)4(C10H8N2)(C2H8N2)2]·H2O, (II), are reported. In the crystal of (I), pairs of [Fe(2,2'-bipy)(CN)4](-) units (2,2'-bipy is 2,2'-bi-pyri-dine) are linked together through ?-? stacking between the pyridyl rings of the 2,2'-bipy ligands to form a graphite-like structure parallel to the ab plane. The three independent water mol-ecules are hydrogen-bonded alternately with each other, forming a ladder chain structure with R 4 (4)(8) and R 6 (6)(12) graph-set ring motifs, while the disordered [N(CH3)4](+) cations lie above and below the water chains, and the packing is stabilized by weak C-H?O hydrogen bonds. The water chains are further linked with adjacent sheets into a three-dimensional network via O-H?O hydrogen bonds involving the lattice water mol-ecules and the N atoms of terminal cyanide groups of the [Fe(2,2'-bipy)(CN)4](-) building blocks, forming an R 4 (4)(12) ring motif. Compound (II) features a two-dimensional {[Fe(2,2'-bipy)(CN)4Cd(en)2]} n layer structure (en is ethyl-enedi-amine) extending parallel to (010) and constructed from {[Fe(2,2'-bipy)(CN)4Cd(en)]} n chains inter-linked by bridging en ligands at the Cd atoms. Classical O-H?N and N-H?O hydrogen bonds involving the lattice water mol-ecule and N atoms of terminal cyanide groups and the N-H groups of the en ligands are observed within the layers. The layers are further connected via ?-? stacking inter-actions between adjacent pyridine rings of the 2,2'-bipy ligands, completing a three-dimensional supra-molecular structure.

Crystal structure of catena-poly[[[(2-eth-oxy-pyrazine-?N)copper(I)]-di-?2-cyanido] [copper(I)-?2-cyanido]].

Project description:In the asymmetric unit of the title coordination compound, {[Cu(CN)(C4H3OC2H5N2)][Cu(CN)]} n , there are two Cu atoms with different coordination environments. One CuI ion is coordinated in a triangular coordination geometry by the N atom of the 2-eth-oxy-pyrazine mol-ecule and by two bridging cyanide ligands, equally disordered over two sites exchanging C and N atoms, thus forming polymeric chains parallel to the c axis. The other Cu atom is connected to two bridging cyanide groups disordered over two sites with an occupancy of 0.5 for each C and N atom, and forming an almost linear polymeric chain parallel to the b axis. In the crystal, the two types of chain, which are orthogonal to each other, are connected by cuprophilic Cu?Cu inter-actions [2.7958?(13)?Å], forming two-dimensional metal-organic coordination layers parallel to the bc plane. The coordination framework is further stabilized by weak long-range (electrostatic type) C-H?? inter-actions between cyano groups and 2-eth-oxy-pyrazine rings.

catena-Poly[[(3-methyl-pyridine)-copper(I)]-?-cyanido-copper(I)-?-cyanido].

Project description:In the title complex, [Cu(2)(CN)(2)(C(6)H(7)N)](n), there are two copper atoms with different coordination environments. One Cu atom (Cu1) is linked to the two cyanide ligands, one N atom from a pyridine ring while the other (Cu2) is coordinated by the two cyanide ligands in a slightly distorted tetra-hedral geometry and linked to Cu1, forming a triangular coordination environment. The Cu atoms are bridged by bidentate cyanide ligands, forming an infinite Cu-CN chain. One cyanide ligand is equally disordered over two sets of sites, exchanging C and N atoms coordinated to both metal atoms. However, one cyanide group is not disordered and it coordinates to Cu1 via the N atom whereas its C-atom counterpart coordinates Cu2. The 3-methyl-pyridine (3MP) ligand coordinates through the N atom to Cu1 as a terminal ligand, which originates from decyanation of 3-pyridyl-acetonitrile under hydro-thermal conditions. Adjacent Cu-CN chains are inter-connected through Cu?Cu inter-actions [2.8364?(10)?Å], forming a three-dimensional framework.

Di-aqua-bis-(ethyl-enedi-amine-?(2) N,N')copper(II) bis-(sulfamerazinate).

Project description:The asymmetric unit of the title compound, [Cu(C2H8N2)2(H2O)2](C11H11N4O2S)2, contains one sulfamerazinate anion in a general position and one half-cation that is located on a center of inversion. The Cu(II) cation shows a strong Jahn-Teller distortion. It is coordinated by four N atoms of two ethyl-enedi-amine ligands in the basal plane and two O atoms at much longer distances in the axial positions in a bipyramidal coordination. In the crystal, the building blocks are connected by N-H?N, O-H?N, N-H?O and O-H?O hydrogen bonding into a two-dimensional network parallel to (001).

Tetra-kis(?(2)-cyanido-?(2)C:N)dicyanido-tetra-kis-[tris-(2-amino-eth-yl)amine-?(3)N,N',N'',N''']tetra-copper(II)iron(II) bis[pentacyanidonitrosoferrate(II)] hexahydrate.

Project description:The asymmetric unit of the title complex, [Cu(4)Fe(CN)(6)(C(6)H(18)N(4))(4)][Fe(CN)(5)(NO)](2)·6H(2)O, comprises a complex [{Cu(tren)CN}(4)Fe(CN)(2)](4+) [tren is tris-(2-amino-eth-yl)amine] cation, which exhibits -1 symmetry with the terminal cyanide ligands oriented trans to each other, and two [Fe(CN)(5)(NO)](2-) nitroprussiate counter-anions. In the crystal, N-H?N hydrogen-bonding inter-actions are observed between H atoms on the primary amine groups of the tren ligand and the terminal cyanide groups of the nitro-prussiate counter-ions. The N atom in the terminal CN ligand of the cation is equally disordered over two positions. The structure also contains disordered lattice water mol-ecules. Their contribution was elimin-ated from the refinement using the procedure described by van der Sluis & Spek (1990 ?).

catena-Poly[[bis-(ethyl-enediamine)copper(II)]-?-sulfato].

Project description:In the title compound, [Cu(SO(4))(C(2)H(8)N(2))(2)](n), the Cu, S and two O atoms lie on a mirror plane. The Cu atom is in a distorted octa-hedral environment and the ethyl-enediamine ligand is in a gauche conformation. The sulfate dianion is bridging, forming a one-dimensional chain. A two-dimensional net parallel to (001) is generated by N-H?O hydrogen bonding between the chains.

catena-Poly[[[tetra-kis-(cyanido-?C)tungstate(IV)]-di-?-cyanido-?C:N-bis-[diaqua-(2,2'-bipyridyl-?N,N')manganese(II)]-di-?-cyanido-?N:C] hexa-hydrate].

Project description:The polymeric title compound, {[Mn(II) (2)W(IV)(CN)(8)(C(10)H(8)N(2))(2)(H(2)O)(4)]·6H(2)O}(n), has a one-dimensional cyanide-bridged Mn(II)-W(IV) bimetallic assembly. The coordination geometry of the W(IV) atom is eight-coordinate square-anti-prismatic and that of each of the Mn(II) atoms is six-coordinate distorted octa-hedral. Two pairs of CN ligands of W(CN)(8) are bridged to two Mn(II) atoms, the remaining CN ligands being terminal. Each Mn(II) atom is additionally coordinated by a bidentate 2,2'-bipyridyl ligand and two water mol-ecules. The crystal structure is stabilized by O-H?O and O-H?N hydrogen bonds.

catena-Poly[[[(diethyl-enetriamine-?³N,N',N'')-copper(II)]-?-cyanido-?²C:N] perchlorate].

Project description:The structure of the title salt, {[Cu(CN)(C?H??N?)]ClO?}(n), is composed of copper-containing cations and perchlor-ate anions. The Cu(II) atom shows a square-pyramidal coordination, with equatorial positions occupied by the cyanide C atom [Cu-C = 1.990?(3)?Å] and the N atoms of the diethyl-enetriamine ligand (average Cu-N = 2.033?Å), while the axial position is occupied by the N atom of a c-glide-related cyanide group. The axial Cu-N distance of 2.340?(3)?Å is longer than the equatorial distances, reflecting Jahn-Teller distortion. The Cu(II) cations are linked by the cyanide groups into infinite chains along the c-axis direction. The refinement included a three-component disordered model for the perchlorate ion. Each minor site is stabilized by hydrogen bonds to N-H donors from four surrounding cations, while one O atom of the major perchlorate site forms hydrogen bonds to three of these cations.
