The title compound, {[Nd(2)(CH(2)CHCOO)(6)(H(2)O)(3)]·3H(2)O}(n), was synthesized by hydro-thermal methods. The structure contains one-dimensional coordination polymers in which two distinct Nd(III) atoms show different coordination modes. One is coordinated by four bidentate acrylate ligands, two of which bridge Nd(III) atoms, and by two O atoms from a further two bridging acrylate ligands. Th...

The title hydrated salt, C30H26N62+·2C9H5N4O-·3H2O, was obtained as an unexpected product from the hydro-thermal reaction between potassium 1,1,3,3-tetra-cyano-2-eth-oxy-propenide, 4,4'-bi-pyridine and iron(II) sulfate hepta-hydrate. The cation lies across a twofold rotation axis in the space group I2/a with the other components all in general positions. In the cation, the H atom linking the py...

In the title compound, C(17)H(16)N(2)O(3)·3H(2)O, the dihedral angle between the mean planes of the benzene and benzimidazole systems is 26.2 (3)°. These groups are slightly twisted around the eth-oxy-methane unit [C-C-O-C torsion angle = 177.64 (15)°]. The crystal packing is stabilized by N-H⋯O, O-H⋯N and O-H⋯O hydrogen-bond inter-actions involving the water mol-ecules. Weak π-π stacking inter...

In the title complex, [Cu(C(16)H(15)NO(3))(C(10)H(8)N(2))]·3H(2)O, the Cu(II) atom is five coordinated by O,N,O'-donor atoms of the Schiff base ligand and by two N atoms of the 2,2'-bipyridine ligand in a distorted square-pyramidal geometry. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (011) by O-H⋯O hydrogen bonds.

In the title complex, [Ni(2)(C(14)H(17)NO(4))(2)(C(12)H(8)N(2))(2)]·4CH(3)OH·3H(2)O, the two Ni(II) ions are bridged by two Schiff base anions, leading to a dinuclear complex. One Ni(II) ion is six-coordinated by four O atoms and two N atoms of two tridentate Schiff base ligands derived from the condensation of l-isoleucine and o-vanillin. The other Ni(II) ion is six-coordinated by four N atoms...
