ABSTRACT
In the title compound, [Zn(C(7)H(6)NO(2))(NO3)(H2O)]n, the Zn atom is coordinated by two nitrate ions, one aqua molecule and two 4-aminobenzoate ions in a distorted octahedral geometry. The structure of the compound exhibits a two-dimensional layer, which is formed by the interconnection of [Zn(C(7)H(6)NO(2))(H2O)]n chains via mu2-nitrate bridges or by the interconnection of [Zn(NO(3))(H2O)]n chains via mu2-4-aminobenzoate bridges.
ABSTRACT
The title compound, {[Ce(C2H6OS)6(H2O)2][NaMo8O26]}n, contains an infinite chain of beta-octamolybdate moieties linked by Na+ ions, and further linked into a two-dimensional network by [Ce(DMSO)6(H2O)2]3+ (DMSO is dimethyl sulfoxide) groups via hydrogen-bond interactions. The Ce and Na atoms are located on a twofold axis and an inversion centre, respectively.
ABSTRACT
The title compound, (C12H11N3)2[Cd2Cl8], consists of two discrete 2-(3-pyridinio)benzimidazolium cations and one [Cd2Cl8]4- anion. The dimeric [Cd2Cl8]4- anion lies about an inversion centre and consists of two distorted [CdCl5] trigonal bipyramids which share a common edge. The two Cd atoms are each coordinated by two mu-Cl atoms and three terminal Cl atoms, with a Cd...Cd separation of 3.9853 (6) A. The packing displays two-dimensional hydrogen-bonded sheets, which are further linked by C-H...Cl contacts and pi-pi stacking interactions to yield a three-dimensional network.
ABSTRACT
In the title compound, [Mn2(C7H6NO2)2(C2H3O2)2(C10H8N2)2], the two MnII atoms are each coordinated by one 2,2'-bipyridyl molecule, one 4-aminobenzoate ion and two acetate ions. The two Mn atoms exhibit different coordination environments: one is coordinated by two N and four O atoms, while the other is coordinated by two N and three O atoms. The two Mn atoms are bridged by two acetate ions in a syn-anti mode, with an Mn...Mn distance of 4.081 (1) A.
ABSTRACT
The title compound, [NaLaMo(8)O(26)(C(3)H(7)NO)(7)](n), contains infinite chains of [Mo(8)O(26)](4-) units supporting dimethylformamide-coordinated La(III) cations and linked by Na(+) cations. The lanthanum center adopts a nine-coordinate geometry and the Na atom is sandwiched between two beta-[Mo(8)O(26)](4-) units.
ABSTRACT
A novel chain molybdenum compound, [[Mo2O6(C6H5NO2)].H2O]n, which was synthesized under hydrothermal conditions, consists of an infinite rail-like chain formed by molybdenum oxide units linked by zwitterionic nicotinic acid ligands. Each Mo atom is coordinated octahedrally by six O atoms and the MoO6 octahedra are linked to one another via edge-sharing to produce a zigzag polymeric chain, with nicotinic acid ligands located, alternately, on each side of the rail-like chain plane.
