Figure 2: The structure of a novel metal–organic framework crystal ZJU-68.
From: Polarized three-photon-pumped laser in a single MOF microcrystal
(a) Crystal structure of ZJU-68 viewed along the crystallographic c direction (C, orange; N, green; O, red; Zn, blue polyhedra). H atoms and solvent molecules are omitted for clarity. In this structure, nine coordination sites of a trinuclear SBU [Zn3O]4+ are completely occupied by six carboxylates and three of nitrogen atoms from the quinoline moieties, which may play a crucial role in the stabilization of the resulting MOF, ZJU-68. (b) The simplified network structure of ZJU-68, displaying 1D channels along the c-axis. Different objects are not drawn to scale. (c) PXRD patterns of ZJU-68 and ZJU-68DMASM, which indicate that the ZJU-68DMASM has the identical framework structure with ZJU-68.
