catena-Poly[hemi{bis[4′-(3-pyridyl)-2,2′:6′,2′′-terpyridine-κ3N1,N1′,N1′′]copper(II)} [cuprate(I)-di-μ2-thiocyanato-κ2N:S;κ2S:N]]

Abstract

The title compound, {[Cu(C20H14N4)2][Cu2(NCS)4]}n, was obtained by reacting copper acetate hydrate, ammonium thiocyanate and 4′-(3-pyridyl)-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 structures. Substitution of a phenyl group with a pyridyl group has no significant effect on the crystal packing which is accomplished by C—H...N and C—H...S hydrogen-bonding interactions.
