Three unique MOFs constructed by 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene and dicarboxylates: From rhombic tetrameric zinc(II) 2D layer to 2D+2D→3D polycatenated frameworks

Doubly interpenetrated indium-tricarboxylate frameworks mediated by small molecules with enhanced porosity

A synthetic strategy of indium-tricarboxylate frameworks by using small molecule regulators has been proposed to obtain four types of In-based coordination polymers with doubly interpenetrated structures.

Structural diversity and catalytic properties of five Co2(COO)4cluster-based coordination polymers modified with R-isophthalic acid (R = H, NO2, CH3, OH andtBu)

By regulation the substituents on 5-position of isophthalic acid, we isolated five Co-based CPs with structural diversity, which all constructed from the Co₂(COO)₄unit. The catalytic properties for Knoevenagel condensation and selective epoxidation of styrene have also been investigated.
