Synthesis, Structures, and Sorption Properties of Two New Metal-Organic Frameworks Constructed by the Polycarboxylate Ligand Derived from Cyclotriphosphazene.

ABSTRACT: Solvothermal reactions of hexakis(4-carboxyphenoxy)cyclotriphospazene (H₆L1) with copper ions in DMF/H₂O produced one complex, {[Cu₆(L1)₂(OH)(H₂O)₃]·guest} _n (1), but with copper ions and auxiliary rigid 4,4-bipyridine (bpy) produced another new complex, namely, {[Cu₃(L1)(bpy)(H₂O)₆]·guest} _n (2). These complexes had been characterized by IR spectroscopy, elemental analysis, and X-ray structural determination. 1 exhibits a 3D anionic structure with the binodal 4,8-connected network with Schläfli symbol {4⁶}₂{4⁹·6¹⁸·8}, consisting of Cu₆ clusters and L1 ligands. In contrast, complex
