Abstract

The structures of two porphyrin-based metal-organic frameworks are reported. The reaction of a carbäoxylic acid functionalised porphyrin with Mn(NO3)2 gives rise to either a one-dimensional or a two-dimensional framework structure depending on the reaction solvent employed. 1 (a = 8.3080(5) Å, b = 14.4466(10) Å, c = 21.8737(14) Å, α = 99.182(6)°, β = 94.118(5)°, γ = 92.562(5)°, P-1, R1 = 0.0894, wR2 = 0.2850) consists of one-dimensional coordination polymers linked through hydrogen-bonded porphyrin molecules leading to a two-dimensional array. In contrast 2 (a = 13.6852(6) Å, b = 41.1655(15) Å, c = 15.4535(6) Å, β = 109.954(5)°, P21/c, R1 = 0.1218, wR2 = 0.3806) consists of two-dimensional sheets, constructed from dinuclear Mn(II) clusters and bridging porphyrin ligands, which, as in 1, are linked through hydrogen-bonded porphyrin molecules but in this case leading to a three-dimensional array. In both structures it is notable that the porphyrin molecules do not bind the Mn(II) cations through the macrocyclic carity, rather both structures.
