catena-Poly[sodium [[tris(3-methylpyridine-2-carboxylato)europate(III)]-μ-3-methylpyridine-2-carboxylato] trihydrate]
In the title structure, {Na[Eu(C(7)H(6)NO(2))(4)]·3H(2)O}(n), the Eu(III) atom is nine-coordin-ated within a slightly distorted tricapped trigonal-prismatic coordination geometry defined by five carboxyl-ate-O atoms and four pyridine-N atoms. One of the carboxyl-ate ligands bridges the Eu cations, forming a one-dimensional coordination polymer along the b axis. The Eu-O bond distances lie withi...
متن کامل2-Methyl-5-nitro-1H-benzimidazol-6-amine dihydrate
The title benzimidazole mol-ecule, C(8)H(8)N(4)O(2)·2H(2)O, is planar with a maximum deviation of 0.079 (2) Å (for one of the O atoms in the nitro group). It crystallized as a dihydrate and inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the uncoordinated water mol-ecules, and the nitro and amine groups, respectively. In the crystal, N-H⋯O, O-H⋯N, O-H⋯O and C-H⋯O hydrogen bonds link the mol...
متن کاملPropane-1,2-diammonium bis(6-carboxypyridine-2-carboxylate) dihydrate
The reaction of propane-1,2-diamine (pn) and pyridine-2,6-dicarboxylic acid (pydcH(2)) in a 1:2 molar ratio in aqueous solution resulted in the formation of the title compound, C(3)H(12)N(2) (2+)·2C(7)H(4)NO(4)·2H(2)O or (pnH(2))(pydcH)(2)·2H(2)O. The structure contains two monoanionic deprotonated forms of pyridine-2,6-dicarboxylic acid molecules (pydcH)(-), a diprotonated propane-1,2-diamine ...

The erbium(III) atom in the title compound, [Er(C(5)H(2)N(2)O(4))(C(5)H(3)N(2)O(4))(C(12)H(8)N(2))(2)]·2H(2)O, is located on a twofold rotation axis and chelated by two 1,10-phenanthroline heterocycles as well as by a 2,4-dihydroxy-pyrimidine-5-car-box-yl-ate monoanion and a 2,4-dihydroxy-pyrimidine-5-car-box-yl-ate dianion in a square-anti-prismatic coordination geometry.
متن کاملBis(2,3,5,6-tetra-2-pyridylpyrazine-κ3 N 2,N 1,N 6)nickel(II) dithiocyanate dihydrate
In the title compound, [Ni(C(24)H(16)N(6))(2)](NCS)(2)·2H(2)O, the central Ni(II) ion is octahedrally coordinated by six N atoms of two tridentate 2,3,5,6-tetra-2-pyridyl-pyrazine ligands (tppz). Two thio-cyanate anions act as counter-ions and two water mol-ecules act as solvation agents. O-H⋯N hydrogen bonds are observed in the crystral structure.
