Two unique isomorphic Zn2Â + and Co2Â +-based metal-organic frameworks comprising octahedral cage

Two isomorphic coordination polymers of 1 and 2 have been synthesized hydrothermally and characterized. Both compounds exhibits one-dimensional rhombus channel with the dimension of about 14.12 × 7.62 Å2. In addition, compound 1 shows strong photoluminescence in DMAc which has the capability of selective sensing of Fe3 + ion.332
