Crystal structure of bis-(2,2':6',2''-terpyridine-?(3) N,N',N'')nickel(II) dicyanidoaurate(I).

ABSTRACT: The title compound, [Ni(C15H11N3)2][Au(CN)2]2, is an ionic compound composed of bis-(2,2':6',2''-terpyridine)-nickel(II) dications and dicyanidoaurate(I) anions in a 1:2 ratio. The two tridentate terpyridine ligands define the coordination of the Ni(2+) cation, resulting in a nearly octa-hedral coordination sphere, although there is not any imposed crystallographic symmetry about the Ni(2+) site. The two nearly linear dicyanidoaurate(I) anions [C-Au-C = 179.0?(2) and 178.2?(2)°] contain a short aurophilic inter-action of 3.1017?(3)?Å. The structure does not demonstrate any ?-? stacking. Non-classical C-H?N inter-actions between the cations and anions build up a three-dimensional network.

Project description:In the centrosymmetric title complex, [Ni(2)(C(14)H(8)O(4)S(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Ni(II) atom is coordinated by two N atoms from one 2,2'-bipyridine ligand, three carboxyl-ate O atoms (one bidentate and one monodentate) from two different disulfanediyldibenzoate ligands and one O atom from a coordinated water mol-ecule in an octa-hedral coordination geometry. The disulfanediyldibenzo-ate dianion bridges two Ni(II )atoms. Adjacent mol-ecules are linked through the coordinated water mol-ecules, forming a O-H?O hydrogen-bonded chain running along the a axis.

(4'-Ethynyl-2,2':6',2''-terpyridine)(2,2':6',2''-terpyridine)-ruthenium(II) bis-(hexa-fluoridophosphate) acetonitrile disolvate.

Project description:The title heteroleptic bis--terpyridine complex, [Ru(C(15)H(11)N(3))(C(17)H(11)N(3))](PF(6))(2)·2CH(3)CN, crystallized from an acetonitrile solution as a salt containing two hexa-fluoridophosphate counter-ions and two acetonitrile solvent mol-ecules. The Ru(II) atom has a distorted octa-hedral geometry due to the restricted bite angle [157.7?(3)°] of the two mer-arranged N,N',N''-tridendate ligands, viz. 2,2':6',2''-terpyridine (tpy) and 4'-ethynyl-2,2':6',2''-terpyridine (tpy'), which are essentially perpendicular to each other, with a dihedral angle of 87.75?(12)° between their terpyridyl planes. The rod-like acetyl-ene group lies in the same plane as its adjacent terpyridyl moiety, with a maximum deviation of only 0.071?(11)?Å from coplanarity with the pyridine rings. The mean Ru-N bond length involving the outer N atoms trans to each other is 2.069?(6)?Å at tpy and 2.070?(6)?Å at tpy'. The Ru-N bond length involving the central N atom is 1.964?(6)?Å at tpy and 1.967?(6)?Å at tpy'. Two of the three counter anions were refined as half-occupied.

?-Adipato-bis-[chlorido(2,2':6',2''-terpyridine)-copper(II)] tetra-hydrate.

Project description:In the title compound, [Cu(2)(C(6)H(8)O(4))Cl(2)(C(15)H(11)N(3))(2)]·4H(2)O, the dinuclear copper complex is located on a crystallographic inversion centre. Each Cu atom is in a distorted square-pyramidal coordination environment, with one O atom of an adipate dianion and three N atoms from the 2,2':6',2''-terpyridine ligand occupying the basal plane, and one chlorine in the apical site. In addition, there is weak Cu-O inter-action opposite of the chlorine with a distance of 2.768?(1)?Å. The adipate ligand adopts a gauche-anti-gauche conformation. The inter-stitial water mol-ecules form hydrogen-bonded tertramers that are connected to the complexes via O-H?O and O-H?Cl hydrogen bonds, thus leading to the formation of tightly hydrogen-bonded layers extending perpendicular to the b-axis direction.

Bis(2,2':6',2''-terpyridine)cobalt(II) bis-(tricyano-methanide).

Project description:The title complex, [Co(C(15)H(11)N(3))(2)](C(4)N(3))(2), is built up from discrete [Co(terpy)(2)](2+) cations (terpy is 2,2':6',2''-terpyridine) and [C(CN)(3)](-) anions. In the cation, the Co(II) atom is coordinated by two terpy mol-ecules, giving a distorted octa-hedral geometry. The tricyano-methanide anions are not directly coordinated to the Co(II) atom, but some weak C-H?N hydrogen bonds involving the terminal N atoms of the tricyaomethanide ions and the terpyridine H atoms link anions and cations building a three-dimensional network.

Project description:The title complex, [Co(C(22)H(14)N(4))(2)]Cl(2), has been synthesized by a solvothermal reaction of the 4'-(4-cyano-phen-yl)-2,2':6',2''-terpyridine ligand with CoCl(2)·6H(2)O. The cobalt(II) ion is six-coordinated by two tridentate ligands in a distorted octa-hedral geometry. The benzene rings form dihedral angles of 30.02?(7) and 30.26?(7)° with the mean planes of the terpyridine ring systems. The chloride anions are statistically disordered over two positions with refined site occupancies of 0.601?(2) and 0.399?(2).

Crystal structure and Hirshfeld surface analysis of tris-(2,2'-bi-pyridine)-nickel(II) bis-(1,1,3,3-tetra-cyano-2-eth-oxy-propenide) dihydrate.

Project description:The title compound, [Ni(C10H8N2)3](C9H5N4O)2·2H2O, crystallizes as a racemic mixture in the monoclinic space group C2/c. In the crystal, the 1,1,3,3-tetracyano-2-ethoxypropenide anions and the water molecules are linked by O-H⋯N hydrogen bonds, forming chains running along the [010] direction. The bpy ligands of the cation are linked to the chain via C-H⋯π(cation) inter-actions involving the CH3 group. The inter-molecular inter-actions were investigated by Hirshfeld surface analysis and two-dimensional fingerprint plots.

Bis(2,2'-bipyridine-?N,N')(croconato-?O,O')nickel(II).

Project description:The title compound, [Ni(C(5)O(5))(C(10)H(8)N(2))(2)], lies across a crystallographic twofold axis, around which two 2,2'-bipyridine (2,2'-bipy) ligands are arranged in a propeller manner. The local geometry of the NiN(4)O(2) coordination core basically adopts an octa-hedral geometry. The mol-ecular twofold axis is along the direction of the mol-ecular dipole moment, and the complex is packed with its dipole moment alternately along the +b and -b directions. The crystal structure is stabilized by inter-molecular C-H?O hydrogen bonds.

Synthesis and crystal structure of catena-poly[[bis[(2,2';6',2''-terpyridine)-manganese(II)]-μ4-penta-thio-dianti-monato] tetra-hydrate] showing a 1D MnSbS network.

Project description:The asymmetric unit of the title compound, {[Mn2Sb2S5(C15H11N3)2]·4H2O} n , consists of two crystallographically independent MnII ions, two unique terpyridine ligands, one [Sb2S5]4- anion and four solvent water mol-ecules, all of which are located in general positions. The [Sb2S5]4- anion consists of two SbS3 units that share common corners. Each of the MnII ions is fivefold coordinated by two symmetry-related S atoms of [Sb2S5]4- anions and three N atoms of a terpyridine ligand within an irregular coordination. Each two anions are linked by two [Mn(terpyridine)]2+ cations into chains along the c-axis direction that consist of eight-membered Mn2Sb2S4 rings. These chains are further connected into a three-dimensional network by inter-molecular O-H⋯O and O-H⋯S hydrogen bonds. The crystal investigated was twinned and therefore, a twin refinement using data in HKLF-5 [Sheldrick (2015 ▸). Acta Cryst. C71, 3-8] format was performed.
