Abstract
A novel cobalt metal-organic framework {[Co2(ltzdc)2(bpe)]·bpe·4H2O}n, MOF (1), has been synthesized by hydrolysis of letrozole (H2ltzdc) and 1,2-di(4-pyridyl)ethylene (bpe) coligand under hydrothermal conditions. Structure of MOF (1) has been determined by single crystal X-ray diffraction. The central Co(II) adopts a distorted tetrahedral coordination configuration and is extended by ltzdc and bpe ligands to form a three-dimensional (3D) pillar-layered framework existing in a 3-fold interpenetrated mode. The powder X-ray diffraction and thermogravimetric analysis demonstrate that the MOF (1) upon heating transforms into MOF (2), that has a retentively porous structure, upon removal of the guest molecules by heating at 300°C in the air. The preliminary antibacterial activity tests indicate MOF (2) as an antibacterial compound against Bacillus subtilis.
