چکیده
In the centrosymmetric dinuclear title complex, [Tb(2)(NO(3))(6)(C(10)H(8)N(2)O(2))(2)(CH(3)OH)(2)], the Tb atoms are bridged by the carboxyl-ate groups of the two 4-(1H-imidazol-3-ium-1-yl)benzoate (iba) ligands. The iba ligand adopts a zwitterionic form with a protonated imidazole group. The Tb atom adopts a distorted tricapped trigonal-prismatic coordination geometry and is coordinated by six O atoms of three chelating nitrate ions, one O atom of the methanol mol-ecule and two O atoms of two iba ligands. The intra-molecular Tb⋯Tb separation is 5.1419 (3) Å. O-H⋯O and N-H⋯O hydrogen bonds connect complex mol-ecules into a two-dimensional network.

The two independent N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(NO(3))(6)], exist in the zwitterionic form. One of these binds to one metal center, whereas the other bridges two metal centers. The La atom is chelated by three nitrate groups and is surrounded by nine O atoms in a coordination environment based on a distorted monocapped square-anti-prism. The dinu...

The title compound, [Mo(2)(C(15)H(15)N(2)O(2))(3)(C(7)H(5)O(2))]·CH(2)Cl(2), has a quadruply bonded Mo(2) (4+) unit equatorially coordinated by three N,N'-bis-(4-μ-meth-oxy-phen-yl)formamidinate (DAniF) ligands and one benzoate anion. The Mo-Mo bond length of 2.0881 (8) Å is typical for quadruply bonded species. The phenyl ring and the connected dimetal chelating ring (Mo(2)O(2)C) are nearly co...

In the title coordination polymer, {[Gd(C(12)H(8)NO(2))(3)(H(2)O)(2)]·H(2)O}(n), the Gd(III) ion is ligated by one bidentate carboxyl-ate group, four monodentate bridging carboxyl-ate O atoms and two water mol-ecules. The resulting GdO(8) polyhedron approximates to a square anti-prism. The bridging ligands link the metal ions into a [100] chain, with each pair of adjacent metal ions being bridg...
