High-resolution synchrotron X-ray powder diffraction study of bis(2-methylimidazolyl)-zinc, C 8 H 10 N 4 Zn (ZIF-8)

The family of zeolitic imidazolate framework (ZIF) compounds is efficient sorbent materials that can be used for catalytic, ion exchange, gas storage, and gas separation applications. A high-resolution reference X-ray powder diffraction pattern for one of the ZIF members, bis(2-methylimidazolyl)-zinc, C 8 H 10 N 4 Zn (commonly known as ZIF-8), was determined using synchrotron diffraction data obtained at the Advanced Photon Source (APS) in Argonne, IL. The sample was confirmed to be cubic I -43 m , with a = 17.01162(6) Å, V = 4932.08 Å 3 , and Z = 12. The reference X-ray powder diffraction pattern has been submitted for inclusion in the Powder Diffraction File (PDF).
