Two new zinc(II) metal-organic frameworks based on 1,4-bis(2-methyl-imidazol-1-yl)butane: synthesis, structures, and properties.

Two new zinc(II) metal-organic compounds, {[Zn(ADC)(bib)]·CH3OH·H2O}n(1) and [Zn(ADA)(bib)]n(2) (H2ADC = 1,3-adamantanedicarboxylic acid, H2ADA = 1,3-adamantanediacetic acid, bib = 1,4-bis(2-methyl-imidazol-1-yl)butane), have been synthesized and characterized. In1, zinc(II) ions are bridged by ADC to form a 1-D chain. The chains are further connected by bib to form a 2-D wave structure. In2, zinc(II) ions are bridged by two ADA to form a 1-D looped chain, and then the 1-D looped chain is connected through bib resulting in a 2-D network. Fluorescent properties, TG analysis, and XRPD for1and2are also measured and discussed. [ABSTRACT FROM PUBLISHER]
