A lanthanide salen "square prism" and a wrapped exo-lanthanide salen "double decker".

An erbium(iii) salen "square prism" and a supramolecular aggregate of exo-erbium(iii) salen "double-decker" cations wrapped by an anionic cuprous cyanide network were prepared from N,N'-ethylene bis[4-(diethylamino)salicylideneimine. Both erbium(iii) edifices show fine-structure near-infrared (NIR) luminescence under the excitation in the visible light area. Here we provide a novel and efficient method for stabilizing non-isolable lanthanide edifices in the solid state.

Photodimerization behaviour of 1D-3D Zn(II) coordination polymers with tetrazolyl styrylpyridine.

The [2 + 2] photodimerization of tetrazolyl styrylpyridine leads to single-crystal-to-single-crystal transformations of four Zn(II) coordination polymers with 1D-3D structures, exhibiting controllable reaction extent, luminescence decrease or blue shift, and a two-step reaction process with a phase transition point.

Zeolitic boron imidazolate frameworks with 4-connected octahedral metal centers.

Solvent selection! The organically templated co-assembly between tetrahedral [B(imidazolate)(4)](-) and [Co(ac)](+) units leads to two previously unknown zeolitic boron imidazolate frameworks with ACO and ABW topologies (denoted BIF-22 and BIF-23; e-urea = ethyleneurea), respectively. BIF-22 is chiral and shows interesting CO(2) selectivity over N(2) and CH(4).
