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 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 ...

In the title coordination polymer, [Sr(C(16)H(13)O(3))(2)(H(2)O)(2)](n), the Sr(II) cation is eight-coordinated by six O atoms from four different 2-(3-benzoyl-phen-yl)propano-ate ligands and two O atoms of two water mol-ecules in a distorted dodeca-hedral geometry. Adjacent Sr(II) cations are bridged by two 2-(3-benzoyl-phen-yl)propano-ate ligands, forming an infinite chain along the b axis; t...
متن کاملSynthesis, crystal structure, quantum chemical calculations, DNA interactions, and antimicrobial activity of [Ag(2-amino-3-methylpyridine)(2)]NO(3) and [Ag(pyridine-2-carboxaldoxime)NO(3)].
[Ag(2-amino-3-methylpyridine)(2)]NO(3) (1) and [Ag(pyridine-2-carboxaldoxime)NO(3)] (2) were prepared from corresponding ligands and AgNO(3) in water/ethanol solutions, and the products were characterized by IR, elemental analysis, NMR, and TGA. The X-ray crystal structures of the two compounds show that the geometry around the silver(I) ion is bent for complex 1 with nitrate as an anion and tr...
