A porous chiral In-MOF with anionic-type diamond network: synthesis, structure and nitrogen gas adsorption

A novel porous chiral In-MOF InH(D-C(10)H(14)O(4))(2) (1) with a left-handed helical channel assembled from D-(+)-camphoric acid (D-H(2)Cam), has been prepared under solvothermal conditions. Single-crystal X-ray diffraction analysis reveals that compound 1 crystallizes in the tetragonal space group P4(3)2(1)2 (no. 96) with parameters: a = 13.8954 angstrom, b = 13.8954 angstrom, c = 17.7870 angstrom, V = 3434.4(7) angstrom (3), Z = 4. The framework feature of compound 1 is characteristic of four-connected anionic-type diamond net with left-handed chiral channel. Moreover, compound 1 exhibits high surface area.
