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:The title compound, {[NdPt(CN)(4)(NO(3))(C(15)H(11)N(3))(H(2)O)(2)]·CH(3)CN·0.5C(15)H(11)N(3)}(n), was isolated from solution as a one-dimensional coordination polymer. The Nd(3+) site in the structure has a ninefold coordination with a distorted tricapped trigonal-prismatic geometry, while the Pt(II) ion is coordinated by four cyanide groups in an almost regular square-planar geometry. Cis-bridging by the tetracyanidoplatinate anions links the Nd(3+) cations, forming the one-dimensional chains. Additionally, each Nd(3+) contains coordin-ation by two water mol-ecules, one tridentate 2,2':6',2''-terpyridine mol-ecule, and one bidentate nitrate anion. 2,2':6',2''-Terpyridine and acetonitrile solvent mol-ecules are incorporated between the chains, the former form π-stacking inter-actions (average inter-planar distance 3.33 Å) with terpyridine mol-ecules located in the chains. Relatively long Pt⋯Pt inter-actions [3.847 (1) Å] are observed in the structure. O-H⋯N and O-H⋯O hydrogen bonding interactions between the consituents consolidates the crystal packing.

catena-Poly[[(2,2'-bipyridine-κN,N')copper(I)]-μ-cyanido-κC:N-[(2,2'-bipyridine-κN,N')copper(I)]-μ-thio-cyanato-κS:N].

Project description:The title compound, [Cu(2)(CN)(SCN)(C(10)H(8)N(2))(2)](n), contains two crystallographically independent Cu(I) atoms, each in a distorted tetra-hedral geometry. Each Cu atom is coordinated by a bidentate chelating 2,2'-bipyridine ligand. A bridging cyanide anion links the two Cu(2,2'-bipyridine) units to form a binuclear unit. Adjacent binuclear units are connected by a thio-cyanate anion into a one-dimensional helical chain along [010]. The cyanide anion is disordered, with each site occupied by both C and N atoms in an occupancy ratio of 0.61 (5):0.39 (5). The S atom of the thio-cyanate anion is also disordered over two sites, with occupancy factors of 0.61 (3) and 0.39 (3). There are π-π inter-actions between the pyridyl rings of neighbouring chains [centroid-centroid distance = 3.82 (1) Å].

catena-Poly[{μ-cyanido-bis-[(4,4'-dimethyl-2,2'-bipyridine-κN,N')copper(I)]}-μ-cyanido-copper(I)-μ-cyanido].

Project description:In the title compound, [Cu(3)(CN)(3)(C(12)H(12)N(2))(2)], two 2,2'-bipyridine N,N'-chelated Cu(I) atoms are linked by a cyanide bridge that lies about a center of inversion; the Cu(I) atom exists in a tetra-hedral coordination geometry. This dinuclear entity is linked to another Cu(I) atom that lies on a twofold rotation axis by another cyanide bridge, these bridges giving rise to the formation of a linear chain motif.

Project description:The title complex, {[Fe(II)Y(III)(CN)(4)(NO(3))(C(10)H(8)N(2))(CH(3)OH)(3)]·CH(3)OH·0.5H(2)O}(n), is built up of ladder-like chains oriented along the c axis. Each ladder consists of two strands based on alternating Fe(II) and Y(III) ions connected by cyanide bridges. Two such parallel chains are connected by additional cyanide anions (the 'rungs' of the ladder), which likewise connect Fe(II) and Y(III) ions, such that each [Fe(bipy)(CN)(4)](2-) (bipy is 2,2'-bipyridine) unit coordinates with three Y(III) ions and each Y(III) ion connects with three different [Fe(bipy)(CN)(4)](2-) units. The Fe(II) atom is six-coordinated in a distorted octa-hedral geometry and the Y(III) atom cation is eight-coordinated in a distorted dodeca-hedral environment. The uncoordinated methanol solvent mol-ecules are involved in hydrogen-bonding inter-actions with the one terminal cyanide group and a coordinated methanol mol-ecule from another [Y(III)(NO(3))(CH(3)OH)(3)](2+) unit. Adjacent ladder-like chains are also held together by hydrogen bonds between the terminal cyanide ligands of the [Fe(CN)(4)(bipy)](2-) units in one chain and the OH donors of CH(3)OH ligands from [Y(III)(NO(3))(CH(3)OH)(3)] units in neighboring chains. The water molecule exhibits half-occupation.

Project description:In the title complex, [Cu(2)(CN)(NCS)(C(12)H(8)N(2))(2)], which was synthesized under hydro-thermal conditions, both Cu(I) atoms have a slightly distorted tetra-hedral geometry. They are coordinated by two N atoms of one 1,10-phenanthroline ligand, one bridging thio-cyanate anion and one bridging cyanide anion. In the crystal structure, infinite helical {Cu-CN-Cu-SCN}(n) chains are formed along [01].

Project description:In the title compound, [Pd(C(8)H(4)O(4))(C(7)H(6)N(2))(2)](n), the Pd atom is tetra-coordinated by two carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra-hedral PdO(2)N(2) geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain. Inter-chain N-H⋯O hydrogen bonds help to stabilize the crystal structure.

μ-Cyanido-κ(2) C:N-dicyanido-κ(2) C-bis-(N-ethyl-ethylenedi-amine-κ(2) N,N')copper(II)copper(I).

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].

Project description:The title polymeric complex, [HgI(2)(C(10)H(14)N(2))](n), was prepared from a solution of nicotine, mercury(II) iodide and 4-cyano-pyridine in dimethyl-formamide. Each nicotine mol-ecule is bonded to two Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming infinite zigzag polymeric chains. The coordin-ation around mercury is completed by two iodide ligands, resulting in a distorted tetra-hedral arrangement.

Project description:In the title compound, [Pd(C(7)H(7)O(3)S)(2)(C(13)H(14)N(2))(2)](n), the metal ion, located on a twofold rotation axis, exhibits a slightly distorted octa-hedral coordination environment, with bond angles that deviate by at most 2.2° from an ideal geometry, completed by two O atoms from two deprotonated p-toluene-sulfonic acid ligands and four N atoms from four 1,3-di-4-pyridylpropane ligands. One of the sulfonate O atoms is disordered over two positions [ratio 0.70 (5):0.30 (5)].

Di-μ-chlorido-bis-{[2-(morpholinometh-yl)phenyl-κC,N]palladium(II)}.

Project description:The title compound, [Pd(2)(C(11)H(14)NO)(2)Cl(2)], has a dimeric structure with Cl atoms bridging the two Pd atoms, one half of the mol-ecule being generated by symmetry due to the crystallographic inversion centre located in the middle of the perfectly planar Pd(2)Cl(2) ring. The five-membered ring adopts an envelope conformation, while the morpholino group has a chair conformation. The geometry around the metal centres is distorted square-planar, as a result of a strong intra-molecular N→Pd coordination trans to a Pd-Cl bond. In the crystal structure, the dimeric structure is strengthened by inter-molecular C-H⋯Cl hydrogen bonds. C-H⋯C(phen-yl) inter-actions link the dimers into a columnar supra-molecular array along the a axis; the dimers are further connected by C-H⋯Ph inter-actions into a three-dimensional supra-molecular arrangement.
