چکیده
In the crystal of the title polymeric compound, [HgI(2)(C(4)H(5)N(3))](n), the Hg(II) cation is located on a twofold rotation axis and is coordinated by two I(-) anions and two 2-amino-pyrazine ligands in a distorted HgI(2)N(2) tetra-hedral geometry. In the crystal, the 2-amino-pyrazine ligand is equally disordered over two positions about an inversion center, and bridges the Hg(II) cations with pyrazine N atoms to form a polymeric chain running along the c axis. In the polymeric chain, the amino groups link to the coordinated I(-) anions via inter-molecular N-H⋯I hydrogen bonds.

The title compound, {[Cu(C(20)H(14)N(4))(2)][Cu(2)(NCS)(4)]}(n), was obtained by reacting copper acetate hydrate, ammonium thio-cyanate and 4'-(3-pyrid-yl)-2,2':6',2''-terpyridine (3-pytpy) under solvothermal conditions. The polymeric complex is isostructural with the 4'-phenyl-2,2':6',2''-terpyridine (phtpy) analogue. All intramolecular distances and angles are very similar for the two structu...

The title complex, [Cu(4)(C(5)H(12)NO)(2)(C(2)H(3)O(2))(6)(C(4)H(8)O)(2)](n), consists of dinuclear [Cu(2)(C(5)H(12)NO)(2)(THF)(2)] (THF is tetra-hydro-furan) and [Cu(2)(CH(3)COO)(4)] units linked through acetate ions, generating parallel one-dimensional polymeric chains propagating in the [10] direction. In the first dinuclear unit, Cu(II) ions related by inversion symmetry are bridged by two ...

The title polymeric complex, [HgI(2)(C(10)H(14)N(2))](n), was prepared from a solution of nicotine, mercury(II) iodide and 4-cyano-pyridine in dimethyl-formamide. Each nicotine mol-ecule is bonded to two Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming infinite zigzag polymeric chains. The coordin-ation around mercury is completed by two iodide lig...

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...

In the title compound, [Ag(2)(C(2)N(3))(2)(C(10)H(8)N(2))](n), the Ag atoms, lying on inversion centers, are separated by 3.3226 (12) Å. Each Ag atom is connected by one bridging 4,4'-bipyridine [Ag-N = 2.177 (4)Å] and a terminal dicyanamide [Ag-N = 2.108 (4) Å]. The Ag-Ag interactions play a key role in constructing a unique neutral polymeric chain.
