چکیده
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 inter-actions [3.2547 (6) Å], forming a two-dimensional layer. The X-ray single-crystal diffraction result is consonant with that of the ab initio X-ray powder diffraction reported by Masciocchi, Moret, Cairati, Sironi, Ardizzoia & La Monica [J. Am. Chem. Soc. (1994). 116, 7668-7676], with only minor deviations of structural parameters.

In the title coordination polymer, [Ag2Cl2(C10H8N2)(C18H15P)2] n , the Ag(I) cation is coordinated by a 4,4'-bi-pyridine N atom, a tri-phenyl-phosphane P atom and two Cl(-) anions in a distorted tetra-hedral geometry. The 4,4-bi-pyridine and Cl(-) anions bridge the Ag(I) cations, forming polymeric chains running along [21-1]. In the crystal, weak C-H⋯Cl inter-actions link the polymeric chains i...

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.
