Microporous Zinc Tris[(4-carboxyl)phenylduryl]amine Framework with an Unusual Topological Net for Gas Storage and Separation

By employment of a new tris­[(4-carboxyl)­phenylduryl]­amine ligand to assembly with the Zn2+ ion, a new topological net built from four coordinatively linked ths nets is first evidenced in the 2-fold-interpenetrating framework FIR-1, which shows potential applications in gas storage and separation.
