چکیده
The title dinuclear compound, [Tb(2)(C(7)H(5)O(3))(6)(H(2)O)(6)]·10H(2)O, lies on a center of inversion and the two Tb(III) atoms are bridged by two 4-hydroxy-benzoate anions; each metal atom is further coordinated by one monodentate anion and chelated by the third anion. The eight-coordinate geometry approximates a square anti-prism. Hydrogen bonds of the O-H⋯O type connect the uncoordinated water mol-ecules to the dinuclear species, forming a three-dimensional network.

The N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(CH(3)COO)(2)(NO(3))(4)], exist in the zwitterionic form. One heterocycle binds to a metal center whereas the other bridges two metal centers. Each La atom is chelated by an acetate and two nitrate groups and is surrounded by nine O atoms in a distorted tricapped trigonal-prismatic coordination environment. The N-H ...

The Zn atom in the title compound, [Zn(C(7)H(5)O(3))(2)(C(12)H(8)N(2))(H(2)O)]·H(2)O, exists in a distorted cis-ZnN(2)O(4) octa-hedral coordination geometry. One of the 4-hydroxy-benzoate anions chelates in a bidentate manner whereas the other is monodentate. The complex mol-ecules are linked through the uncoordinated water mol-ecules into a hydrogen-bonded sheet structure.
