Poly[tetraaqua-di-μ4-malonato-barium(II)cadmium(II)]
In the title complex, [BaCd(C(3)H(2)O(4))(2)(H(2)O)(4)](n), the Ba(II) atoms, located on crystallographic twofold axes, adopt slightly distorted square-anti-prismatic coordination geometries, while the Cd(II) atoms, which lie on crystallographic centres of symmetry, have a distorted octa-hedral coordination. Each malonate dianion binds two different Cd(II) atoms and two different Ba(II) atoms. ...

In the title complex, [CoK(2)(C(3)H(2)O(4))(2)(H(2)O)(4)](n), the Co atom is located on a position with site symmetry 2/m, the K atom and one water mol-ecule are located on a mirror plane, and the malonate and one water mol-ecule are located on a twofold rotation axis. The K(I) atom is seven-coordinated by four carboxyl-ate O atoms from four malonate ligands and by three water O atoms, forming ...

In the title coordination polymer, [Na(2)(C(4)H(3)N(2)O(2)S)Cl(H(2)O)(2)](n), the Na(I) ion lies on a twofold rotation axis and the chloride anion on an inversion center. The Na(I) ion is six-coordinated by two O atoms from two zwitterionic 2-mercaptopyrimidine-4,6-diolate ligands (mm2 symmetry), two water O atoms (m symmetry) and two Cl atoms in a distorted octa-hedral geometry. Adjacent Na(I)...
متن کاملPoly[tetraaqua-μ4-squarato-di-μ3-squarato-disamarium(III)]
The structure of the title compound, [Sm(2)(C(4)O(4))(3)(H(2)O)(4)](n), consists of infinite-chain structural units, built from edge-sharing samarium SmO(7)(H(2)O)(2) polyhedra and linked via bis-monodendate squarate (sq1) groups. The chains extend along [100] in a zigzag mode and are interconnected by bis-chelating squarate (sq2) ligands into layers parallel to (101). Inter-layer hydrogen bond...

In the title compound, [Y(2)(C(4)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), the flexible succinate anion assumes a gauche conformation and bridges the eight-coordinated Y atoms, generating two-dimensional layers parallel to (010). The coordination polymer layers are linked into a three-dimensional framework by the rigid oxalate ligands. The oxalate ions are located on a center of inversion. Inter-mo...
