Synthesis of the two isomers of heteroleptic Rh12L6L '(6) metal-organic polyhedra by screening of complementary linkers

We have synthesised and characterised the two possible isomers of heteroleptic trigonal antiprismatic M12L6L '(6) MOPs by screening reactions of rhodium acetate with different pairs of complementary dicarboxylate linkers. The resulting 12 new MOPs (eight of isomer A + four of isomer B) are microporous in the solid state, exhibiting Brunauer-Emmett-Teller (BET) surface areas as high as 770 m(2) g(-1).
