Trans-Bis(perchlorato-?O)tetra-kis(1H-pyrazole-?N)copper(II).

ABSTRACT: The title compound, [Cu(ClO(4))(2)(C(3)H(4)N(2))(4)], was obtained unexpectedly by the reaction of copper(II) perchlorate hexa-hydrate with equimolar amounts of 1-chloro-1-nitro-2,2,2-tripyrazolylethane in methanol solution. The crystal structure comprises octa-hedrally coordinated Cu(2+) ions, located on an inversion centre, with four pyrazole ligands in the equatorial plane. The average Cu-N distance is 2.000?(1)?Å. Two perchlorate ions are coordinated to copper in trans positions [Cu-O = 2.4163?(11)?Å].

trans-Bis(nitrato-?O)tetra-kis-(1-vinyl-1H-imidazole-?N(3))copper(II).

Project description:In the title compound, [Cu(NO(3))(2)(C(5)H(6)N(2))(4)], the Cu(II) ion is located on an inversion centre. It features a Jahn-Teller-distorted octa-hedral coordination geometry, defined by four N atoms of four 1-vinyl-imidazole ligands in the equatorial plane and two nitrate O atoms in the axial positions. The nitrate anion is disordered over two sets of sites in a 0.801?(6):0.199?(6) ratio. In the crystal, the complex mol-ecules are linked by weak inter-molecular C-H?O and C-H?? inter-actions.

trans-Bis(thio-cyanato-?N)tetra-kis-(3,4,5-trimethyl-1H-pyrazole-?N)nickel(II)-3,4,5-trimethyl-1H-pyrazole (1/1).

Project description:In the title compound, [Ni(NCS)(2)(C(6)H(10)N(2))(4)]·C(6)H(10)N(2), the asymmetric unit comprises a Ni(II) complex and a co-crystallised mol-ecule of 3,4,5-trimethyl-1H-pyrazole (PzMe(3)). The Ni(II) atom is coordinated by four PzMe(3) mol-ecules and two thio-cyanate anions to define a trans N(4)S(2) distorted octa-hedral geometry. A number of intra-molecular N-H?N, N-H?S and C-H?N inter-actions contribute to the stability of the complex. The crystal structure is stabilized by inter-molecular N-H?S inter-actions, which link neighbouring mol-ecules into chains along the a axis.

Tetra-kis(dimethyl-ammonium) trans-di-chloridobis[5,5'-(pyrazine-2,3-diyl)bis(1H-tetra-zol-1-ido-?N(1))]copper(II).

Project description:The title compound, (C(2)H(8)N)(4)[Cu(C(6)H(2)N(10))(2)Cl(2)], consists of an anionic complex which is composed of a Cu(II) ion surrounded by four N atoms from two pyrazine-2,3-diylbis(1H-tetra-zol-1-ide) ligands, and two Cl(-) atoms in a trans-Cl(2)N(4) coordination geometry; the Cu(II) atom lies on a site of symmetry 2/m. The Cu-Cl distance of 2.8719?(5)?Å is long due to the Jahn-Teller distortion of the d(9) electron configuration of Cu(II) ion. The tetra-zole and pyrazine rings make an N-C-C-N torsion angle of 38.25?(17)°. The charge of the anionic complex is balanced by four dimethyl-ammonium cations, which inter-act with the anionic complexes via N-H?N and N-H?Cl hydrogen bonds.

Project description:The title compound, [Cu(4)Cl(6)O(C(10)H(10)N(2))(4)], contains four Cu(II) atoms which are bridged by six chloride anions.

The geometry at each Cu(II) atom is distorted trigonal-bipyramidal, with the three Cl(-) ions in the equatorial plane and the N and O atoms in the axial positions.

Project description:The structure of the title compound, [Ni(NCS)(2)(C(6)H(8)N(2))(4)], consists of isolated mol-ecules of [Ni(NCS)(2)(Aim)(4)] (Aim = 1-allyl-imidazole), which contain a distorted octa-hedral NiN(6) chromophore.

Weak C-H⋯N inter-actions contribute to the crystal packing stability.

cyclo-Tetra-kis(μ-3-acetyl-4-methyl-1H-pyrazole-5-carboxyl-ato-κN,O:N,O)tetra-kis[aqua-copper(II)] tetra-deca-hydrate.

Project description:The title compound, [Cu(4)(C(7)H(6)N(2)O(3))(4)(H(2)O)(4)]·14H(2)O, a tetra-nuclear [2 × 2] grid-type complex with S4 symmetry, contains four Cu(II) atoms which are bridged by four pyrazole-carboxyl-ate ligand anions and are additionally bonded to a water molecule.

The geometry at each Cu(II) atom is distorted square-pyramidal, with the two N and two O atoms in the equatorial plane and O atoms in the axial positions. O-H⋯O hydrogen-bonding interactions additionally stabilize the structure. One of the uncoordinated water molecules shows half-occupancy.

Tetra-kis(1H-benzimidazole-?N)(nitrato-?O)copper(II) nitrate.

Project description:In the title salt, [Cu(NO(3))(C(7)H(6)N(2))(4)]NO(3), one nitrate anion is coordinated to the Cu(II) atom, which is also coordinated by the N atoms of four N-heterocycles.

The cation lies on a twofold rotation axis; the coordinated nitrate anion is also disordered about this symmetry element. The lattice anion is also disordered about a twofold rotation axis. In the crystal, the cations are linked to the coordinated and free anions by N-H?O hydrogen bonds.

Chloridotris(3,5-dimethyl-1H-pyrazole-?N)(formato-?O)copper(II)-dichlorido-bis(3,5-dimethyl-1H-pyrazole-?N)copper(II) (2/1).

Project description:The asymmetric unit of the title compound, [Cu(CHO(2))Cl(C(5)H(8)N(2))(3)](2)·[CuCl(2)(C(5)H(8)N(2))(2)] or 2[A]·[B], contains one A mol-ecule and one half-molecule of B, located on a centre of inversion. The Cu(II) environments in A and B are different. In A, the Cu(II) atom is coordinated by three N atoms from three 3,5-dimethyl-1H-pyrazole (L) ligands, one O atom from a formate ligand and a chloride anion in an axial position [Cu-Cl = 2.4275?(7)?Å] in a distorted tetra-gonal-pyramidal geometry. The Cu(II) atom in B is coordinated by two N atoms from two L ligands and two chloride anions [Cu-Cl = 2.2524?(6)?Å] in a distorted square-planar geometry. In the crystal, inter-molecular N-H?O hydrogen bonds link mol-ecules A into centrosymmetric dimers. Inter-molecular N-H?Cl hydrogen bonds further link these dimers with the B mol-ecules, forming chains propagating in [101].

Project description:In the title compound, [Cd(ClO(4))(2)(C(15)H(18)N(4))(4)], the Cd(II) ion is coordinated in a slightly distorted octa-hedral environment by two trans monodentate perchlorate ligands and four 1-(2-pyrid-yl)-4-(4-pyridylmeth-yl)piperazine (pmpp) ligands. In the crystal structure, mol-ecules are organized into layers parallel to the ab plane by C-H?O inter-actions. Similar inter-actions promote the stacking of these layers into the three-dimensional crystal structure.
