Zeolitic boron imidazolate frameworks with 4-connected octahedral metal centers.
Solvent selection! The organically templated co-assembly between tetrahedral [B(imidazolate)(4)](-) and [Co(ac)](+) units leads to two previously unknown zeolitic boron imidazolate frameworks with ACO and ABW topologies (denoted BIF-22 and BIF-23; e-urea = ethyleneurea), respectively. BIF-22 is chiral and shows interesting CO(2) selectivity over N(2) and CH(4).
