Catena-Poly[[[bis-(methanol-?O)bis-(seleno-cyanato-?N)manganese(II)]-?-1,2-bis-(pyridin-4-yl)ethane-?(2) N:N'] 1,2-bis-(pyridin-4-yl)ethane monosolvate].

ABSTRACT: The reaction of manganese seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) leads to the title compound, {[Mn(NCSe)2(C12H12N2)(CH3OH)2]·C12H12N2} n . The Mn(II) cation is coordinated by two N-bonded seleno-cyanate anions, two bpa ligands and two O-bonded methanol mol-ecules, within a slightly distorted octa-hedral geometry. The Mn(II) cations and the non-coordinating N-donor ligands are located on centers of inversion while the coordinating N-donor co-ligands are located on a twofold rotation axis. In the crystal, the Mn(II) cations are linked into chains along the c-axis direction by the bpa ligands. The chains are further connected via a non-coordinating bpa ligand into layers parallel to (3-10) via O-H?N hydrogen-bonding inter-actions.

Project description:The title compound, {[Fe(NCSe)2(C12H12N2)(H2O)2]·2C12H12N2·2H2O} n , was obtained by the reaction of iron(II) sulfate hepta-hydrate and potassium seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) in water. The Fe(II) cation is coordinated by two N-bonded seleno-cyanate anions, two water mol-ecules and two 1,2-bis-(pyridin-4-yl)ethane (bpa) ligands in a slightly distorted octa-hedral geometry. In addition, two non-coordinating bpa mol-ecules and two water mol-ecules are present. The Fe(II) cation is located on a center of inversion while the coordinating bpa ligand is located on a twofold rotation axis. The Fe(II) cations are linked by the bpa ligands into chains along the b-axis direction, which are further connected into layers perpedicular to the c axis by O-H⋯N and O-H⋯O hydrogen bonds to the non-coordin-ating bpa and the water mol-ecules. The crystal studied was twinned by pseudo-merohedry (180° rotation along c*; contribution of the minor twin component 3.7%).

Project description:In the crystal structure of the title compound, {[Mn(NCSe)2(C12H10N2)(CH3OH)2]·C12H10N2} n , the Mn(II) cation is coordin-ated by two terminal N-bonded seleno-cyanate anions, two methanol mol-ecules and two 1,2-bis-(pyridin-4-yl)eth-ene (bpe) ligands within a slightly distorted octahedral geometry. The Mn(II) cations are linked into chains along the c-axis direction by the bpe ligands, which are further connected by inter-molecular O-H⋯N hydrogen bonding between the methanol H atoms and additional bpe mol-ecules that are not coordinated to the metal atoms. The Mn(II) cation and both crystallographically independent bpe ligands are located on centers of inversion, whereas the seleno-cyanate and methanol ligands occupy general positions.

Poly[[bis-[?2-1,2-bis-(pyridin-4-yl)ethene-?(2) N:N']bis-(thio-cyanato-?N)cobalt(II)] 1,2-bis-(pyridin-4-yl)ethene monosolvate dihydrate].

Project description:The asymmetric unit of the title compound, {[Co(NCS)2(C12H10N2)2]·C12H10N2·2H2O} n , consists of two independent Co(II) cations, four distinct thio-cyanate anions, six 1,2-bis-(pyridin-4-yl)ethene (4-bpe) mol-ecules and four lattice water mol-ecules. The Co(II) cations are each coordinated by two N-bonded thio-cyanate anions and four 4-bpe ligands within a slightly distorted CoN6 octa-hedron. The two independent Co(II) cations are linked by the 4-bpe ligands into two distinct layers, parallel to the ac and bc planes, that inter-penetrate. From this arrangement, channels are formed in which non-coordinated 4-bpe and lattice water mol-ecules are hydrogen-bonded into chains that elongate in the c-axis direction.

A triclinic polymorph of poly[[bis-[μ-1,2-bis-(pyridin-4-yl)ethene-κ(2)N:N']bis-(thio-cyanato-κN)cobalt(II)] 1,2-bis-(pyridin-4-yl)ethene monosolvate].

Project description:In the crystal structure of the title compound, [Co(NCS)(2)(C(12)H(10)N(2))(2)]·C(12)H(10)N(2), the Co(II) cations are octa-hedrally coordinated by two terminally N-bonded thio-cyanate anions and four 1,2-bis-(pyridin-4-yl)ethene (bpe) ligands. The asymmetric unit consists of three crystallographically independent Co(II) cations, six thio-cyanate anions and six coordinating bpe ligands in general positions. Additionally, three non-coordin-ating bpe ligands are present in the asymmetric unit with two of them located on a center of inversion. The Co(II) cations are connected by the bpe ligands into layers parallel to the bc plane. The crystal investigated was non-merohedrically twinned, with a fractional contribution of 0.261 (2) for the minor domain.

Project description:In the title coordination compound, {[Zn(C(7)H(4)BrO(2))(2)(C(12)H(10)N(2))]·CH(3)CN}(n), the Zn(II) atom is four-coordinated in a distorted tetra-hedral environment by two carboxyl-ate O atoms from two different 4-bromo-benzoate (bpe) ligands and two N atoms from two symmetry-related 1,2-bis-(4-pyrid-yl)ethene ligands. The Zn(II) atoms are bridged by the bpe ligands, which lie across centres of inversion, forming a zigzag chain along [001]. The void space of each unit cell is occupied by an acetonitrile solvent mol-ecule, which is connected to the complex mol-ecule by a weak C-H⋯N hydrogen bond.

catena-Poly[[[di-aqua-bis-[1,2-bis-(pyridin-4-yl)diazene]copper(II)]-μ-1,2-bis-(pyridin-4-yl)diazene] bis-(perchlorate)].

Project description:In the title compound, {[Cu(C10H8N4)3(H2O)2](ClO4)2} n , the coordination environment of the cationic Cu(II) atom is distorted octa-hedral, formed by pairs of symmetry-equivalent 1,2-bis-(pyridin-4-yl)diazene ligands, bridging 1,2-bis-(pyridin-4-yl)diazene ligands and two non-equivalent water mol-ecules. The 1,2-bis-(pyridin-4-yl)diazene mol-ecules form polymeric chains parallel to [-101] via azo bonds which are situated about inversion centres. Since the Cu(II) atom is situated on a twofold rotation axis, the monomeric unit has point symmetry 2. The perchlorate anions are disordered in a 0.536 (9):0.464 (9) ratio and are acceptors of water H atoms in medium-strong O-H⋯O hydrogen bonds with graph set R 4 (4)(12). The water mol-ecules, which are coordinated to the Cu(II) atom and are hydrogen-bonded to the perchlorate anions, form columns parallel to [010]. A π-π inter-action [centroid-centroid distance = 3.913 (2) Å] occurs between pyridine rings, and weak C-H⋯O inter-actions also occur.

Crystal structures of three co-crystals of 1,2-bis-(pyridin-4-yl)ethane with 4-alk-oxy-benzoic acids: 4-eth-oxy-benzoic acid-1,2-bis-(pyridin-4-yl)ethane (2/1), 4-n-propoxybenzoic acid-1,2-bis(pyridin-4-yl)ethane (2/1) and 4-n-but-oxy-benzoic acid-1,2-bis-(pyridin-4-yl)ethane (2/1).

Project description:The crystal structures of three hydrogen-bonded co-crystals of 4-alk-oxy-benzoic acid-1,2-bis-(pyridin-4-yl)ethane (2/1), namely, 2C9H10O3·C12H12N2, (I), 2C10H12O3·C12H12N2, (II), and 2C11H14O3·C12H12N2, (III), have been determined at 93, 290 and 93 K, respectively. In (I), the asymmetric unit consists of one 4-eth-oxy-benzoic acid mol-ecule and one half-mol-ecule of 1,2-bis-(pyridin-4-yl)ethane, which lies on an inversion centre. In (II) and (III), the asymmetric units each comprise two crystallographically independent 4-alk-oxy-benzoic acid mol-ecules and one 1,2-bis-(pyridin-4-yl)ethane mol-ecule. In each crystal, the two components are linked by O-H⋯N hydrogen bonds, forming a linear hydrogen-bonded 2:1unit of the acid and the base. Similar to the structure of 2:1 unit of (I), the units of (II) and (III) adopt nearly pseudo-inversion symmetry. The 2:1 units of (I), (II) and (III) are linked via C-H⋯O hydrogen bonds, forming tape structures.

catena-Poly[(E)-4,4'-(ethane-1,2-di-yl)dipyridinium [[bis-(thio-cyanato-κN)ferrate(II)]-di-μ-thio-cyanato-κN:S;κS:N]].

Project description:In the crystal structure of the title compound, {(C(12)H(14)N(2))[Fe(NCS)(4)]}(n), the iron(II) cation is coordinated by four N-bonded and two S-bonded thio-cyanate anions in a distorted octa-hedral coordination mode. The asymmetric unit consists of half an iron(II) cation and half a protonated (E)-4,4'-(ethane-1,2-di-yl)dipyridinium dication, each located on a centre of inversion. In addition, there are two thio-cyanate anions in general positions. The crystal structure consists of Fe-(NCS)(2)-Fe chains in which each iron(II) cation is additionally coordinated by two terminal N-bonded thio-cyanate anions. Non-coordinating dipyridinium dications are present between the thiocyanatoferrate(II) chains and are connected to the anions via N-H⋯N and N-H⋯S hydrogen-bond interactions.

Chlorido[N,N'-dibenzyl-N,N'-bis-(pyridin-2-ylmeth-yl)ethane-1,2-diamine]-copper(II) perchlorate methanol monosolvate.

Project description:In the title solvated mol-ecular salt, [CuCl(C(28)H(30)N(4))]ClO(4)·CH(3)OH, the Cu(2+) ion is coordinated by the N,N',N'',N'''-tetra-dentate ligand and a chloride ion, generating a very distorted square-based pyramidal CuN(4)Cl coordination geometry with the Cl(-) ion in the basal position. In the crystal, the solvent mol-ecules and anions are linked by weak O-H?O hydrogen bonding.
