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

ABSTRACT: 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.

Project description:In the title compound, [Cu(2)(C(10)H(8)N(2))(2)(C(58)H(52)N(2)P(4))](BF(4))(2), the dinuclear cation lies on an inversion centre.

?-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.

In the cation, the Cu(II) atom shows a slightly distorted square-pyramidal coordination geometry provided by a pair of ?-OH(-) anions and by the N atoms of a chelate tmen ligand in the basal plane. The apical position is statistically occupied by the O atom of a half-occupancy water mol-ecule. The F atoms of the anion are disordered over three sets of sites with occupancies of 0.598?(9):0.269?(6):0.134?(8). The crystal packing is governed by ionic forces as well as by O-H?F hydrogen bonds.

Project description:Reaction of the ligand 2,2',2'',2'''-{[pyrazine-2,3,5,6-tetra-yltetra-kis-(methyl-ene)]tetra-kis-(sulfanedi-yl)}tetra-acetic acid (H4L1), with NiCl2 leads to the formation of a binuclear complex, (μ-2,2',2'',2'''-{[pyrazine-2,3,5,6-tetra-yltetra-kis-(methyl-ene)]tetra-kis-(sulfanedi-yl)}tetra-acetato-κ5 O,S,N 1,S',O':κ5 O'',S'',N 4,S''',O''')bis[aqua-nickel(II)] hepta-hydrate, {[Ni2(C16H16N2O8S4)(H2O)2]·7H2O} (I). It crystallizes with two half mol-ecules in the asymmetric unit. The complete mol-ecules are generated by inversion symmetry, with the center of the pyrazine rings being located at crystallographic centres of inversion. The ligand coordinates two NiII ions in a bis-penta-dentate manner and the sixfold coordination sphere of each nickel(II) atom (NiS2O3N) is completed by a water mol-ecule. The complex crystallized as a hepta-hydrate. The binuclear complexes are linked by Owater-H⋯Ocarbon-yl hydrogen bonds, forming layers parallel to the (101) plane. This layered structure is additionally stabilized by weak C-H⋯O hydrogen bonds. Further O-H⋯O hydrogen bonds involving binuclear complexes and solvent water mol-ecules, together with weak C-H⋯S hydrogen bonds, link the layers to form a supra-molecular framework.

Crystal structure of μ-oxalodi-hydroxamato-bis-[(2,2'-bipyrid-yl)(di-methyl sulfoxide-κO)copper(II)] bis-(perchlorate).

Project description:The centrosymmetric binuclear complex, [Cu2(C2H2N2O4)(C10H8N2)2(C2H6OS)2](ClO4)2, contains two copper(II) ions, connected through an N-deprotonated oxalodi-hydroxamic acid dianion, two terminal 2,2'-bi-pyridine ligands, and two apically coordinating dimethylsulfoxide mol-ecules. Two non-coordinating perchlorate anions assure electrical neutrality. The copper(II) ions in the complex dication [Cu2(C10H8N2)2(μ-C2H2N2O4)(C2H6SO)2](2+) are in an O2N3 square-pyramidal donor environment, the Cu-Cu separation being 5.2949 (4) Å. Two hydroxamate groups in the deprotonated oxalodi-hydroxamic acid are located trans to one each other. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the complex cations to the perchlorate anions. Further C-H⋯O hydrogen bonds combine with π-π contacts with a centroid-to-centroid separation of 3.6371 (12) Å to stack the mol-ecules along the a-axis direction.

Octa-kis(2-chloro-benz-yl)di-?(2)-hydroxido-di-?(3)-oxido-bis-(2-phenyl-acetato)tetra-tin(IV).

Project description:The asymmetric unit of the title compound, [Sn(4)(C(7)H(6)Cl)(8)(C(8)H(7)O(2))(2)O(2)(OH)(2)], comprises one-half of the centrosymmetric tin(IV) complex. ?(3)-Oxide and ?(2)-hydroxide bridges link the four five-coordinate Sn(IV) atoms to generate three fused four-membered Sn-O-Sn-O rings in a ladder-like structure. The two endocyclic Sn atoms each bind to two ?(3)-oxide anions and a ?(2)-hydroxide ligand, together with two 2-chloro-benzyl groups. The exocyclic Sn atoms each carry a monodentate phenyl-acetate ligand, two 2-chloro-benzyl groups, and ?(3)-oxide and ?(2)-hydroxide ligands. Both types of Sn atoms adopt a distorted trigonal-bipyramidal coordination geometry. The mol-ecular conformation is stabilized by intra-molecular O-H?O inter-actions involving the ?(2)-hydroxide ligands and the C=O group of the phenyl-acetate ligand.
