چکیده
In the title compound, {(C(10)H(11)N(3))[Zn(3)(C(8)H(4)O(4))(4)]·2H(2)O}(n), divalent Zn atoms are linked into trinuclear units featuring tetra-hedral, octa-hedral and distorted tetrahedral, octahedral and square-pyramidal coordination geometries. These trinuclear units are connected by isopthalate dianions into [Zn(3)(isophthalate)(4)](n) (2n-) anionic layers, which aggregate into the three-dimensional structure via hydrogen-bonding pathways mediated by doubly protonated 4,4'-imino-dipyridinium cations and water mol-ecules of crystallization. One solvent water mol-ecule was found to be disordered over two positions, each with a 50% site-occupancy factor.

In the title salt, {(C(10)H(11)N(3))[V(4)O(8)(PO(4))(2)]}(n), cubane-like [V(4)O(8)](4+) clusters are connected by phosphate anions into anionic [V(4)P(2)O(16)](n) (2n-) layers. These aggregate into the three-dimensional structure via N-H⋯O hydrogen-bonding mechanisms imparted by 4,4'-imino-dipyridinium dications situated between the layers.

In the title compound, [CuNa(3)(CH(3)CO(2))(5)(CH(3)COOH)(H(2)O)(2)](n), the Cu(II) atom lies on an inversion center and is coordinated by four O atoms from four acetate ligands, leading to a square-planar geometry. One Na(I) atom, lying on an inversion center, is coordinated by four O atoms from four acetate ligands and two bridging water mol-ecules in a distorted octa-hedral geometry. The oth...

The title complex, [Pr(2)(C(8)H(7)O(3))(6)(C(12)H(8)N(2))(2)](n), which has an inversion centre midway between the two Pr(III) atoms of the structural unit, forms a one-dimensional polymer bridged alternately by either two bidentate, or two bidentate and two terdentate, phenoxy-acetate carboxyl-ate groups. Each Pr(III) atom is thus nine-coordinated by two N atoms of a 1,10-phenanthroline ligand...

The coordination polymer [Zn(2)(C(10)H(8)O(5))(2)(H(2)O)(3)](n) adopts a layer structure in which the two independent Zn(II) ions exist in trigonal-bipyramidal coordination geometries. One carboxyl-ate dianion binds to a monoaqua-coordinated metal ion through the aliphatic carboxyl-ate end and to the diaqua-coordinated metal ion through the aromatic carboxyl-ate end; the other dianion binds in ...

In the title polymer, [Co(3)(C(6)H(8)O(4))(3)(C(19)H(12)N(4))(2)](n), two adipate dianions (C(6)H(8)O(4) (2-)) occupy general positions and two are situated on different inversion centres. The two on general positions bind through their four O atoms to five 2-phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene-chelated Co(II) ions, whereas the two on special positions bind to only four.
