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...

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 asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-a...
متن کاملcatena-Poly[[trimethyltin(IV)]-μ-2-(3-thienyl)acetato]
The title compound, [Sn(CH(3))(3)(C(6)H(5)O(2)S)](n), forms an infinite chain structure parallel to [100]. There are two mol-ecules of the complex in the asymmetric unit. The geometry of the Sn atoms in both mol-ecules is distorted trigonal-bipyramidal. The S and C atoms of the thio-phene rings in both mol-ecules are disordered over two sites with site-occupancy factors 0.799 (9)/0.201 (9) and ...
متن کاملSynthesis of some new anils: part 1. Reaction of 2-hydroxy-benzaldehyde and 2-hydroxynaphthaldehyde with 2-aminopyridene and 2-aminopyrazine.
New Schiff bases derived from 2-aminopyridene and 2-aminopyrazine have been synthesized. The UV-Visible spectra of the compounds have been investigated in acetonitrile and toluene. The compounds were in tautomeric equilibrium (enol-imine O- H...N, keto-amine O...H-N forms) in polar and nonpolar solvents. For some derivatives the keto-amine form was observed in both toluene and acetonitrile. 1H-...
