The synthesis and structure of a mixed zinc/copper metal-organic framework material Zn3(BDC)3[Cu(Pyen)] · (DMF)5(H2O)5 (H2BDC ) 1,4 benzenedicarboxylic acid and PyenH2 ) 5-methyl-4-oxo-1,4-dihydro-pyridine-3-carbaldehyde) is reported. Desolvation provides a bimodal porous structure Zn3(BDC)3[Cu(Pyen)] (M′MOF 1) with narrow porosity (
