Tetrakis(2,2′-bipyridine)di-μ3-hydroxido-bis(μ-2-oxidobenzoato)tetracopper(II) dinitrate tetrahydrate

چکیده
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 μ(2)-phenolate O atoms from the salicylate ligands and two μ(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.

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 lin...

In the centrosymmetric title compound, [Co(C6H12N4O3)2](NO3)2·4H2O, the Co(II) ion, lying on an inversion center, is O,N,O'-chelated by two nitrilo-triacetamide mol-ecules, forming a distorted octa-hedral geometry. In the crystal, extensive O-H⋯O and N-H⋯O hydrogen bonds link the complex cations, nitrate anions and lattice water mol-ecules into a three-dimensional network.
