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...

In the title complex, [Ca(C(10)H(6)NO(2))(2)(H(2)O)(2)](n), the Ca(II) ion is eight-coordinated by six carboxyl-ate O atoms from four separate quinoline-3-carboxyl-ate ligands, two of which are bidentate chelate and two bridging, and two water mol-ecules in a distorted square-anti-prismatic geometry. The bridging groups form a polymeric chain substructure extending along the c axis, the chains ...

The title compound, [Sr(C(10)H(6)NO(2))(2)(H(2)O)(2)](n), contains an eight-coordinate Sr(II) ion displaying a distorted square-anti-prismatic geometry, two quinoline-3-carboxyl-ate ligands and two terminal water mol-ecules. The Sr(II) atom is surrounded by six carboxyl-ate O atoms from four separate quinoline-3-carboxyl-ate ligands and two O atoms from two coordinated water mol-ecules. The bri...

The polymeric structure of the title compound {[Li(C(6)H(3)N(2)O(4))(H(2)O)]·H(2)O}(n), contains two symmetry-independent Li(I) complex units, both having distorted trigonal-bipyramidal coordination environments. The Li(I) ions are bridged by both the N and O atoms of the ligands, generating two symmetry-independent polymeric chains propagating along the b-axis direction. In both ligands, the s...

The title complex, [Tb(2)(C(6)H(4)NO(2))(6)(H(2)O)(4)](n), was isolated under hydro-thermal conditions using the ligand pyridine-4-carb-oxy-lic acid (HL) and Tb(2)O(3). The deprotonated L(2-) ligands adopt bridging coordination modes. The central Tb(III) atom is bridged by L(2-) ligands, forming a polymeric chain parallel to the a axis. Supra-molecular O-H⋯N inter-actions link the chains, build...
