In the centrosymmetric dinuclear title complex, [Ag(2)(CF(3)SO(3))(2)(C(11)H(11)N(3)S)(2)], the Ag(I) atom is coordinated by two N atoms from two 4-methyl-2-(2-pyridyl-methyl-sulfan-yl)pyrimidine ligands and one O atom from a trifluoro-methane-sulfonate anion in a distorted T-type coordination geometry. The ligand adopts a bidentate bridging coordination(More)
The mol-ecule of the title binuclear copper(II) complex, [Cu(2)(CH(3)COO)(4)(C(5)H(5)NO)(2)], occupies a special position on a crystallographic inversion centre; the coordination environment of the Cu(II) atom is slightly distorted square-pyramidal and is made up of four O atoms belonging to four acetate groups in the basal plane with the O atom of pyridine(More)
The tile compound, C(12)H(12)N(2)O(2)S(2), lies on an inversion center. The two pyridyl rings are parallel to each other. The structure is devoid of any classical hydrogen bonds due to lack of appropriate donors and acceptors for such bonds. However, non-classical hydrogen bonds of the types C-H⋯O and C-H⋯S stabilize the structure.
In the title compound, catena-poly[cadmium(II)-bis-(μ-5-am-ino-1,3,4-thia-diazole-2-thiol-ato)-κ(2)N(3):S(2);κ(2)S(2):N(3)], [Cd(C(2)H(2)N(3)S(2))(2)](n), the Cd(II) ion is coordinated by two N atoms of the 1,3,4-thia-diazole rings from two ligands and two S atoms of sulfhydryl from two other ligands in a slightly distorted tetra-hedral geometry.

In the title compound, 2C(9)H(7)N(2)O(4) (+)·SO(4) (2-)·H(2)O, the sulfate S atom and the water O atom reside on a crystallographic twofold axis. In the crystal, the component species are linked by N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network structure. An intramol-ecular O-H⋯O link is seen in the cation.
In the title complex, [Cd(C(6)H(4)NO(3))(2)(H(2)O)(4)], the Cd(II) atom is situated on a crystallographic centre of inversion. The Cd(II) atom shows a slightly distorted octa-hedral geometry and is coordinated by four O atoms from water mol-ecules and two O atoms from deprotonated carboxyl groups of nicotinic acid N-oxide ligands. The mononuclear complex(More)
In the title compound, C(18)H(16)N(2)O(2)S(2), the benzene ring makes dihedral angles of 7.41 and 86.59° with the two outer pyridine N-oxygen rings. Two short intramolecular C-H⋯S contacts occur. The crystal packing is stabilized by C-H⋯O hydrogen bonds, C-H⋯π inter-actions and weak π-π staking inter-actions [centroid-centroid distance 3.7596 (7) Å].
The title compound, [Ag(C(3)H(3)N(2))](n), has an infinite helical chain structure in which each pyrazolate group bridges two Ag(I) atoms related by a 2(1) axis with an intra-chain Ag⋯Ag separation of 3.3718 (7) Å. Each Ag(I) center is linearly coordinated by two N atoms [N-Ag-N angle = 169.98 (14)°]. The chains are held together by inter-chain Ag⋯Ag(More)
In the title centrosymmetric binuclear complex, [Y(2)(C(10)H(6)NO(2))(6)(H(2)O)(4)]·2H(2)O, each Y(III) atom is nine-coordin-ated by nine O atoms from five ligands and two water mol-ecules in a slightly distorted monocapped square-anti-prismatic coordination environment. The Y(III) atoms are separated by a distance of 4.0363 (9) Å. The ligands coordinate in(More)
The title compound, [Cu(C(9)H(4)N(2)O(4))(H(2)O)(5)]·5H(2)O, contains one crystallographically independent Cu(II) atom and one 1H-benzimidazole-5,6-dicarboxyl-ate (bdc) ligand, along with five coordinated and five uncoordinated water mol-ecules. The Cu(II) atom is six-coordinated by one N atom from the bdc ligand and five O atoms from water mol-ecules,(More)
