Polypseudorotaxane architecture of poly-bis[4-(N-benzyl- pyridinium)]piperazine-hexa-thiocyanato-di-cadmium(ii) with 2-D honeycomb-like [Cd(SCN)3]nn− anionic polymeric framework†
Abstract
An unusual, honeycomb-like cadmium-tri-thiocyanate polymeric framework was found in the studied hybrid material of general formula (L2+)n[Cd(SCN)3]2n2n− (3), where L2+ is bis[4-(N-benzylpyridinium)]piperazine dication. The perforated coordination net forms due to a template effect of the organic dications which reside in the holes penetrating the net in a polyrotaxane-like manner. The salt (L2+)(SCN)2·2H2O (4) was studied for comparison.
