Tetra-aqua-bis-{5-[4-(imidazol-1-yl-?N)phen-yl]tetra-zolido}manganese(II).

ABSTRACT: In the title complex, [Mn(C(10)H(7)N(6))(2)(H(2)O)(4)], the Mn(2+) cation is located on a twofold rotation axis and is coordinated by two N atoms from two 5-[4-(imidazol-1-yl)phen-yl]tetra-zolide ligands and four O atoms from four water mol-ecules, displaying a distorted MnN(2)O(4) octa-hedral geometry. The crystal structure is stabilized by intermolecular O-H?N hydrogen bonds involving the coordinated water mol-ecules and the N atoms of the tetra-zolide group.

Project description:The title compound, [Mn(C(6)H(4)N(5)O)(2)(H(2)O)(4)], is isotypic with its Zn, Ni and Cd analogues reported recently. In the crystal, the Mn(II) cations are coordinated by four O atoms from four aqua ligands and two N atoms from two 5-(pyridin-4-yl)tetra-zolide N(5)-oxide ligands in a distorted octa-hedral coordination environment.

The discrete complex mol-ecules are arranged in alternating rows parallel to [100] and are linked by O-H?N and O-H?O hydrogen bonds into a three-dimensional network.

The perchlorate anions also function as inter-unit links through water O-H?O hydrogen bonds which, together with water O-H?O(carbon-yl) inter-actions, give a three-dimensional framework structure.

Bis(?-5-carboxyl-atotetra-zolido)bis-[aqua-(2,2'-bipyrid-yl)cadmium(II)].

Project description:In the title dinuclear Cd(II) complex, [Cd(2)(C(2)N(4)O(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], each Cd atom is in a slightly distorted octa-hedral coordination by two N atoms and one O atom of two 1H-tetra-zole-5-carboxyl-ate (TZC) ligands, two N atoms of a 2,2'-bipyridyl ligand and one water O atom.
