A novel microporous rhodium(H) coordination polymer, [Rh-2(H2TCPP)] (1) (H2TCPP = 4,4',4",4"'-(21H,23H-porphine-5,10,15,20-tetrayl)tetrakis benzoic acid) was synthesized. The complex I showed high porosity of the micropores of 7.3 Angstrom. The amount of nitrogen adsorbed by 1 was 2.87 mole per mole of Rh, which is about three times that of rhodium(II) fumarate and rhodium(II) terephthalate. Complex I also showed high turnover frequencies for the hydrogenation of ethylene and propene at ca. 200 K.
