Catena-Poly[copper(II)-bis-(?-2-ethyl-5-methyl-imidazole-4-sulfonato-?N,O:O)].

ABSTRACT: In the title compound, [Cu(C(6)H(9)N(2)O(3)S)(2)](n), the copper(II) ion sits on an inversion center and is chelated by the imidazole N and sulfonate O atoms of two ligands in equatorial positions. O atoms of adjacent mol-ecules coordinate in the axial positions. Jahn-Teller tetra-gonal distortion is evident in the coordination geometry [Cu-N and Cu-O equatorial distances of 1.971?(3) and 2.045?(2)?Å, respectively, with a Cu-O axial distance of 2.433?(3)?Å]. The structure is propagated by an infinite chain of eight-membered (Cu-O-S-O)(2) ring systems along the a axis. Only N-H?O hydrogen bonding exists between the chains.

Project description:The title compound, [Cu(C(2)O(4))(C(5)H(8)N(2))(2)](n), is composed of one-dimensional linear chains running parallel to the a axis. In the chain, trans-[Cu(imidazole)(2)](2+) units are sequentially bridged by bis-bidentate oxalate ligands, resulting in an octa-hedral CuO(4)N(2) donor set. The Cu⋯Cu separation through the oxalate bridge is 5.620 (5) Å. Both the Cu atoms and the C-C bond of the oxalate bridge are bis-ected by inversion centres.

Project description:In the solid state, the title compound, [Zn(C(8)H(4)O(4))(C(4)H(6)N(2))(2)](n), exhibits the existence of polymeric zigzag chains extending along the a axis. Each Zn(II) ion is coordinated by two N atoms [Zn-N = 1.996 (6) and 2.032 (5) Å] and two O atoms [Zn-O = 1.930 (4) and 1.976 (4) Å] in a distorted tetra-hedral geometry. Weak C-H⋯O inter-actions contribute to the crystal packing stability.

catena-Poly[[bis-(1-methyl-1H-imidazole-κN)zinc]-μ-3-nitro-phthalato-κO:O].

Project description:In the title complex, [Zn(C(8)H(3)NO(6))(C(4)H(6)N(2))(2)](n), the carboxyl-ate groups of the 3-nitro-phthalate dianion ligand coordinate the Zn(II) ion in a bis-monodentate mode. The Zn(II) ion shows distorted tetra-hedral coordination as it is bonded to two O atoms from the carboxyl-ate groups of symmetry-related 3-nitro-phthalate anions and two N atoms of two independent 1-methyl-imidazole mol-ecules. The bridging 3-nitro-phthalate ligand allows the formation of one-dimensional chains in the c direction. The crystal structure is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

catena-Poly[[bis-(μ(2)-4-amino-benzene-sulfonato-κO:O)disilver]-bis-(μ(2)-4,4'-bipyridine-κN:N')].

Project description:In the title compound, [Ag(2)(C(6)H(6)NO(3)S)(2)(C(10)H(8)N(2))(2)](n), the Ag(I) atom is four-coordinated by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) and two O atoms from two independent 4-amino-benzene-sulfonate (ABS) ligands. The two inter-chain Ag(I) atoms are bridged by two independent ABS ligands through weak Ag-O bonds and Ag⋯Ag attractions, forming a ladder-like chain coordination polymer [Ag(2)(ABS)(2)(bipy)(2)](n) parallel to [001], which is further linked to generate a two-dimensional structure via N-H⋯O hydrogen-bonding inter-actions.

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)].

catena-Poly[[bis-(N-ethyl-ethylene-di-amine-κN,N')copper(II)]-μ-cyanido-κN:C-[dicyanido-κC-palladium(II)]-μ-cyanido-κC:N].

Project description: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 polymeric complex, [Ni(C(2)H(6)NO(3)S)(2)](n), the Ni(II) ion occupies a special position on an inversion centre and displays a slightly distorted octa-hedral coordination geometry, being linked to four sulfonate O atoms and to two N atoms of the taurine ligands. The sulfonate groups doubly bridge symmetry-related Ni(II) centers, forming polymeric chains along the a axis.

catena-Poly[di-μ3-bromido-bis-[(1-ethyl-1H-imidazole-κN (3))disilver(I)]].

Project description:The asymmetric unit of the title coordination complex, [Ag2Br2(C5H8N2)2] n , comprises a monodentate 1-ethyl-imida-zole ligand, an Ag(+) cation and a μ3-bridging Br(-) anion, giving a distorted tetra-hedral AgNBr3 stereochemistry about the Ag(+) cation [Ag-N = 2.247 (2) Å and Ag-Br = 2.7372 (4)-2.7523 (4) Å]. Two bridging bromide anions generate the dimeric [Ag2Br2(C5H8N)2] repeat unit [Ag⋯Ag = 3.0028 (5) Å], while a third Br(-) anion links the units through corner sharing in an inversion-related Ag2Br2 association [Ag⋯Ag = 3.0407 (4) Å], generating a one-dimensional ribbon step-polymer structure, extending along the c axis.

catena-Poly[copper(I)-bis(μ-trifluoro-methane-sulfonato-κO:O')-copper(I)-bis(μ-trimethyl trithio-phosphite)-κP:S;κS:P].

Project description:The title compound, [Cu(2)(CF(3)SO(3))(2)(C(3)H(9)PS(3))(2)](n), crystallizes as infinite chains in which two trimethyl trithio-phosphite ligands and two trifluoro-methane-sulfonate anions bridge the essentially tetra-hedrally coordinated Cu(I) ions in an alternating fashion. The P and one S atom of each trimethyl trithio-phosphite ligand are employed for coordination. The mol-ecular structure exhibits the rare motif of copper(I) bridged by two trifluoro-methane-sulfonate anions generating eight-membered rings.

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.
