Microwave assisted hydrothermal synthesis of a novel CuI-sulfate-pyrazine MOF

A new 3D coordination copper polymer has been synthesised under microwave heating hydrothermal conditions. Microwave irradiation reduces the time of reaction considerably, suggesting the effectiveness of this methodology in the synthesis of metal-organic frameworks. It is noteworthy that microwave assisted synthesis produces monocrystals suitable for X-ray diffraction studies, reducing reaction time and with higher yield than the classical hydrothermal procedures. The compound presented here, [Cu2(pyz)2(SO4)(H2O)2]n (pyz = pyrazine), has been crystallographically characterised to be a threefold interpenetrated three-dimensional coordination (10,3)-b network.
