The geometry control of secondary building units (SBU) depend on solvent exchange in Zn-MOF

Abstract

The tuning of status of SBU is one of the challenges for proper target properties in coordination chemistry. The reaction of Zn2+ ion and carboxylate generate Zn4O(COO)6 SBU frequently. Here we examined reactions of Zn(NO3)3●6H2O and H3BTB ligand in DMF and obtained 2-fold interpenetrated structure composed of 3-c BTB ligand and 6-c Zn4O(COO)6 metal cluster, thereby, it is 3,6-c ant net. It is tuned that coordination geometry of Zn4O(COO)6 SBU on synthesized metal-organic frameworks (MOFs) depend on exchanging solvents. We will be discussed analysis of MOFs based on solvent exchange.
