Tetra-kis(2,2'-bipyrid-yl)dichlorido-di-?(3)-hydroxido-di-?(2)-hydroxido-tetra-copper(II) dinitrate hexa-hydrate.

ABSTRACT: The tetra-nuclear copper(II) title complex, [Cu(4)Cl(2)(OH)(4)(C(10)H(8)N(2))(4)](NO(3))(2)·6H(2)O, has a crystallographically imposed centre of symmetry. The metal atoms display a distorted tetragonal-pyramidal coordination geometry, and are linked by two ?(2)- and two ?(3)-hydroxo groups, assuming a chair-like conformation for the Cu(4)O(2) core. In the crystal, the complex mol-ecules are linked into a three-dimensional network by inter-molecular O-H?O, O-H?Cl, C-H?O and C-H?Cl hydrogen bonds and ?-? stacking inter-actions with centroid-centroid separations of 3.724?(2) and 3.767?(3)?Å.

The tetra-nuclear copper(II) title complex, [Cu(4)Cl(2)(OH)(4)(C(10)H(8)N(2))(4)](NO(3))(2)·6H(2)O, has a crystallographically imposed centre of symmetry. The metal atoms display a distorted tetragonal-pyramidal coordination geometry, and are linked by two μ(2)- and two μ(3)-hydroxo groups, assuming a chair-like conformation for the Cu(4)O(2) core. In the crystal, the complex mol-ecules are linked into a three-dimensional network by inter-molecular O-H⋯O, O-H⋯Cl, C-H⋯O and C-H⋯Cl hydrogen bonds ...[more]

Tetra-kis(2,2'-bipyrid-ine)di-?(3)-hydroxido-bis(?-2-oxidobenzoato)tetra-copper(II) dinitrate tetra-hydrate.

Project description:The tetra-nuclear title complex, [Cu(4)(C(7)H(4)O(3))(2)(OH)(2)(C(10)H(8)N(2))(4)](NO(3))(2)·4H(2)O, has a crystallographically imposed centre of symmetry. The Cu(II) atoms display a distorted square-pyramidal coordination geometry and are linked by two ?(2)-phenolate O atoms from the salicylate ligands and two ?(3)-hydroxo groups, forming a Cu(4)O(4) core that adopts a 'stepped-cubane' geometry. In the crystal, the cations are linked by O-H?O hydrogen bonds to the nitrate anions, which are in turn connected via O-H?O inter-actions to centrosymmentric water tetra-mers.

Poly[[diaqua-bis-(μ2-4,4'-bipyrid-yl)cobalt(II)] dinitrate tetra-hydrate].

Project description:The title compound, {[Co(C10H8N2)2(H2O)2](NO3)2·4H2O} n , (C10H8N2 = 4,4'-bipyridine = 4,4'-bpy) is a layered coordination polymer built up from a cationic square grid extending in (101) enclosing uncoordinating nitrate ions and water mol-ecules. The Co(II) ion has site symmetry 2 and one of the 4,4'-bpy ligands is generated by twofold symmetry [two N atoms and two C atoms lie on the rotation axis and the dihedral angle between the pyridine rings is 45.66 (5)°]. The other 4,4'-bpy ligand is generated by a crystallographic inversion center. The Co(II) ion exhibits a slightly distorted octa-hedral coordination geometry defined by two O atoms of two coordinating water mol-ecules and four N atoms from four bridging 4,4'-bpy ligands. The structure is consolidated by O-H⋯O, C-H⋯O and C-H⋯N hydrogen bonds.

Two pairs of CN ligands of W(CN)(8) are bridged to two Mn(II) atoms, the remaining CN ligands being terminal. Each Mn(II) atom is additionally coordinated by a bidentate 2,2'-bipyridyl ligand and two water mol-ecules. The crystal structure is stabilized by O-H?O and O-H?N hydrogen bonds.

4,4',6,6'-Tetra-methyl-2,2'-bipyrimidine hexa-hydrate.

Project description:In the title compound, C(12)H(14)N(4)·6H(2)O, the two pyrimidine rings make a dihedral angle of 5.285 (6)°. Inter-molecular O-H⋯O hydrogen bonds link the six water mol-ecules, generating edge-fused four-, five- or six-membered ring motifs and forming two-dimensional sheets. The sheets are stabilized by the formation of O-H⋯N hydrogen bonds between the water mol-ecules and the bipyrimidine mol-ecules, resulting in a three-dimensional network.
