چکیده
The reaction of copper(I) iodide with 1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one (L, C13H19NOS) in aceto-nitrile/di-chloro-methane results in a crystalline coordination polymer, namely poly[bis-{μ2-1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one}tetra-μ3-iodido-tetra-copper(I)], [Cu4I4L2] n . The asymmetric unit comprises two ligand mol-ecules, four copper(I) ions and four iodide ions. Inter-estingly, the O atoms are bound to the soft copper(I) ions. The stair-step clusters of Cu and I atoms in the asymmetric unit are linked repeatedly, giving rise to infinite chains along [100]. Neighbouring infinite chains are linked through the L mol-ecules, forming a two-dimensional brick-wall structure. These two-dimensional networks are stacked alternately along [001]. Additionally, there are inter-molecular C-H⋯I hydrogen bonds and C-H⋯π inter-actions between the ligands.

In the title coordination polymer, [Cu(2)I(2)(C(14)H(14)N(4))(C(18)H(15)P)(2)](n), the Cu(I) atom is coordinated by two I atoms, one P atom and one N atom in a fairly regular tetra-hedral arrangement. A crystallographic inversion centre generates a Cu(2)I(2) diamond with a Cu-Cu separation of 3.0120 (5) Å. The complete N,N'-(1-pyridin-4-yl-ethethyl-idene)-hydrazine mol-ecule is also generated b...

The title coordination polymer, [CdBr(2)(C(8)H(8)N(4))(2)](n), arose from a layer-separated diffusion synthesis at room temperature. The title compound is isotypic with the I and Cl analogues. The Cd atom, located on an inversion center, is coordinated by two bromide ions and four N atoms (two from triazole rings and two from pyridyl rings) in a distorted trans-CdBr(2)N(4) octa-hedral arrangeme...
