Tetra-aqua-bis-(1,10-phenanthroline-?N,N')strontium 5,5'-diazene-diyl-ditetra-zolide.

ABSTRACT: The title complex, [Sr(C(12)H(8)N(2))(2)(H(2)O)(4)](C(2)N(10)), contains an [Sr(phen)(2)(H(2)O)(4)](2+) cation (phen is 1,10-phenanthroline) and a 5,5'-diazenediylditetra-zolide anion (site symmetry 2). The Sr(2+) cation (site symmetry 2) is coordinated by four N atoms from two chelating phen and four water mol-ecules. In the crystal structure, the water mol-ecules and the N atoms in the tetra-zolide rings form an extensive range of O-H?N hydrogen bonds which link the complex into a two-dimensional structure. An adjacent layer further yields a three-dimensional supramolecular network by offset face-to-face ?-? stacking inter-actions of the phen ligands [with centroid-centroid distances of 3.915?(2) and 4.012?(2)?Å]. The two bridging N atoms of the anion are equally disordered about the twofold rotation axis.

Project description:The title compound, [Co(C(12)H(8)N(2))(H(2)O)(4)](2)[Co(H(2)O)(6)](C(11)H(7)O(8))(2)·4H(2)O, was obtanied by the reaction of cobalt acetate with 3,5-bis-(carb-oxy-meth-oxy)benzoic acid and 1,10-phenanthroline. The asymmetric unit contains one tetra-aqua-(1,10-phenanthroline)cobalt(II) cation, one half of a hexa-aqua-cobalt(II) cation that is completed by inversion symmetry, one 3,5-bis-(carboxyl-atometh-oxy)benzoate trianion and two lattice water mol-ecules. The two Co(II) atoms each show a slightly distorted octa-hedral coordination (CoO(6) and CoO(4)N(2)). The cations, anions and lattice water mol-ecules are linked by an intricate network of O-H?O hydrogen bonds into a three-dimensional structure.

Project description:The title compound, [Cu(3)(C(5)HN(2)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, is a trinuclear copper(II) complex in which two centrosymmetrically related pyrazole-3,5-dicarboxyl-ate(3-) and 1,10-phenanthroline ligands bind three Cu(II) atoms, with one Cu(II) atom located on a center of symmetry. In each complex, there are four coordinated water mol-ecules and two solvent water mol-ecules, which participate in extensive hydrogen-bond patterns. These inter-actions, as well as ?-? inter-actions between neighbouring 1,10-phenanthroline ligands [shortest atom-to-atom distance = 3.363?(3)?Å], extend the crystal structure into a three-dimensional supra-molecular network.
