چکیده
The crystal structure of the title compound, [Cu(C(2)N(3))(C(2)H(3)N)(2)](n), features zigzag chains along the a axis that consist of alternating [Cu(MeCN)(2)] and dicyanamide units, the latter acting as bidentate ligands via both terminal N atoms. The Cu atom shows a slightly distorted tetra-hedral coordination sphere. The anionic and neutral ligands lie on different mirror planes (perpendicular to the b and a axis, respectively), while the Cu atom is situated on their inter-section. The asymmetric unit comprises one fourth of the formula unit.

In the title compound, [Cd(C(2)N(3))(2)(C(6)H(6)N(2)O(3))(2)](n), the Cd(II) ion (site symmetry ) adopts a distorted trans-CdO(2)N(4) octa-hedral environment, being coordinated by two O-bonded 3-methyl-4-nitro-pyridine N-oxide ligands and four dicyanamide (dca) anions. The bridging dca anions lead to a polymeric chain propagating in [100].

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.

The title compound, [Co(C(2)N(3))(2)(C(3)H(7)NO)(2)](n), is a triclinic polymorph of the previously reported monoclinic structure [Tong et al. (2003 ▶). Acta Cryst. E59, m405-m407]. The Co(II) ion lies on an inversion centre and adopts an almost regular octa-hedral N(4)O(2) coordination geometry. Adjacent Co(II) atoms are connected by two bridging dicyanamide ligands, resulting in the formation...
