Di-μ-chlorido-bis-[dichlorido(3,3',5,5'-tetra-methyl-4,4'-bipyrazol-1-ium-κN)copper(II)] dihydrate.

ABSTRACT: The structure of the centrosymmetric title compound, [Cu(2)Cl(6)(C(10)H(15)N(4))(2)]·2H(2)O, consists of a dimeric [{(HMe(4)bpz)CuCl(3)}(2)] unit (HMe(4)bpz is 3,3',5,5'-tetra-methyl-4,4'-bipyrazol-1-ium) with two solvent water molecules. Each [HMe(4)bpz](+) cation is bonded to a CuCl(3) unit through a Cu-N dative bond, effectively making square-planar geometry at the Cu atom. Two of these units then undergo a face-to-face dimerization so that the Cu atoms have a Jahn-Teller distorted square-pyramidal geometry with three chlorides and an N atom in the basal plane and one chloride weakly bound in the apical position. Several N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds form a three-dimensional network.

Project description:In the title compound, [Cu(2)Cl(4)(C(11)H(16)N(4))](n), the Cu atom is coordinated by two N atoms of two 3,3',5,5'-tetra-methyl-4,4'-methyl-enedipyrazole (H(2)mbdpz) ligands, two bridging Cl atoms and one terminal Cl atom, forming a square-pyramidal geometry. The bridging Cl atoms and the bridging H(2)mbdpz ligands connect the Cu atoms to build up an extended one-dimensional chain. The chains are further connected through N-H⋯Cl hydrogen bonds to build up a two-dimensional layer in the (011) plane. An inversion centre lies between every pair of adjacent Cu atoms.

Project description:In the title compound, {[Zn(2)(C(16)H(4)I(2)O(8))(H(2)O)(4)]·2H(2)O}(n), two crystallographically independent Zn(II) atoms are each located on a twofold rotation axis. Both Zn(II) atoms are in distorted octa-hedral coordination geometries: one is coordinated by six O atoms from four carboxyl-ate groups, while the other is coordinated by two carboxyl-ate groups and four water mol-ecules. The tetra-carboxyl-ate ligand mol-ecules connect the Zn(II) atoms, completing a three-dimensional metal-organic framework. O-H⋯O hydrogen bonds link the metal-organic framework with the uncoord-inated water mol-ecules.

The dihedral angles between the carboxyl-ate groups and the adjacent phenyl ring are 71.31?(3) and 16.67?(3)°, while the carboxyl-ate groups are oriented at a dihedral angle of 72.01?(3)°. In the crystal structure, inter-molecular O-H?O and bifurcated O-H?(O,O) hydrogen bonds link the mol-ecules to form a three-dimensional supra-molecular network.

Project description:In the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](ClO(4))(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-ecules. A twofold inter-penetrated primitive cubic supra-molecular network is formed by the inter-action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4'-bipyridine mol-ecules.

Crystal structure and Hirshfeld surface analysis of 4,4'-di-meth-oxy-biphenyl-3,3',5,5'-tetra-carb-oxy-lic acid dihydrate.

Project description:In the crystal of the title compound, C18H14O10·2H2O, the arene rings of the biphenyl moiety are tilted at an angle of 24.3 (1)°, while the planes passing through the carboxyl groups are rotated at angles of 8.6 (1) and 7.7 (1)° out of the plane of the benzene ring to which they are attached. The crystal structure is essentially stabilized by O-H⋯O bonds. Here, the carboxyl groups of neighbouring host mol-ecules are connected by cyclic R 2 2(8) synthons, leading to the formation of a three-dimensional network. The water mol-ecules in turn form helical supra-molecular strands running in the direction of the crystallographic c-axis (chain-like water clusters). The second H atom of each water mol-ecule provides a link to a meth-oxy O atom of the host mol-ecule. A Hirshfeld surface analysis was performed to qu-antify the contributions of the different inter-molecular inter-actions, indicating that the most important contributions to the crystal packing are from H⋯O/O⋯H (37.0%), H⋯H (26.3%), H⋯C/C⋯H (18.5%) and C⋯O/O⋯C (9.5%) inter-actions.

μ-4,4'-Bipyridine-κN:N'-bis-[aqua-(4,4'-bi-pyridine-κN)(l-valinato-κN,O)copper(II)] dinitrate dihydrate.

Project description:In the title dinuclear complex, [Cu(2)(C(5)H(10)NO(2))(2)(C(10)H(8)N(2))(3)(H(2)O)(2)](NO(3))(2)·2H(2)O, each of the two l-valinate anions chelates a Cu(II) center through the amino N and carboxyl-ate O atom, forming a five-membered ring. A 4,4'-bipyridine mol-ecule bridges two water-coordinated Cu atoms, each of which is connected to another 4,4'-bipyridine, giving rise to a square-pyramidal coordination geometry for the Cu(II) centers. The dinuclear dications, nitrate anions and uncoord-inated water mol-ecules are linked into a two-dimensional structure.

The Pt(IV) atom is six-coordinated in an octa-hedral configuration by two N atoms of the 4,4'-dimethyl-2,2'-bipyridine ligand and four terminal Cl atoms. In the crystal structure, there are weak π-π inter-actions between pyridine rings, with a centroid-centroid distance of 4.365 (3) Å.

Diammonium 1,1',3,3'-tetra-methyl-2,2',4,4',6,6'-hexa-oxoperhydro-5,5'-bipyrimidine-5,5'-diide monohydrate.

Project description:In the title hydrated salt, 2NH(4) (+)·C(12)H(12)N(4)O(6) (2-)·H(2)O, the two hexa-hydro-pyrimidine rings in the dianion are inclined to one another at a dihedral angle of 62.76?(5)°. In the crystal structure, the anions and water mol-ecules are linked into sheets parallel to the bc plane by inter-molecular O-H?O hydrogen bonds and sustained by C-H?O contacts. The linking of the anions and water mol-ecules with the cations by N-H?O hydrogen bonds creates a three-dimensional extended network. The crystal structure is further stabilized by very weak C-H?? inter-actions.

2-Oxo-1,2-dihydro-pyrimidin-3-ium di-μ-chlorido-bis-{dichloridobis[pyrimidin-2(1H)-one-κN]cuprate(II)} dihydrate.

Project description:The asymmetric unit of the title compound, (C(4)H(5)N(2)O)(2)[Cu(2)Cl(6)(C(4)H(4)N(2)O)(2)]·2H(2)O, consists of one cation, one half of a centrosymmetric dianion and one water mol-ecule. The centrosymmetric dianion formed by dimerization in the crystal structure has neutral pyrimidin-2-one ligands coordinated to each copper(II) centre through Cu-N bonds. The Cu atoms each have a distorted trigonal bipyramidal geometry, with the N atom of the pyrimidin-2-one ligand in an axial position, and dimerize by sharing two equatorial Cl atoms. N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds connect the anions, cations and water mol-ecules, forming a three-dimensional network.
