With the help of a heterometallic approach, an unstable channel-type framework {[Cu4Cl(CPT)(4)]center dot(NO3)(3)center dot 5DMF}(n) (1, HCPT = 4-(4H-1,2,4-triazol-4-yl)benzoic acid, DMF = N,N-Dimethylformamide) is structurally modified into a robust channel-type framework {[InCu(OH)(CPT)(2)]center dot(NO3)(2)center dot(DMF)(4)}(n) (2) via embedding independent indium based units into the Cu(II)-organic framework, in which the 1D In(III)-chains and 1D Cu(II)-chains coexist. Although both MOFs have similar framework structures, the activated heterometallic MOF 2 exhibits a BET surface area of 1032 m(2)/g, which is extraordinary high compared with that of the activated 1. In addition, the gas sorption property of MOF 2 around room temperature has also been investigated.
