The title compound [Mn(Phen)(p-MBA)(2)](n) (1) was synthesized via the hydrothermal reaction of KMnO4 and NaOH with phen and p-methybenzoic acid (p-MBA) in water. The title compound was characterized by elemental analysis and infrared spectra. The crystal of 1 crystallizes in orthorhombic, space group Pbcn with a = 24.132(1), b = 10.404(0), c = 9.386(0) angstrom, V = 2356.65(13) angstrom(3), Z = 4, C28H22MnN2O4, M-r = 505.42; D-c = 1.424 g/cm(3), F(000) = 1044 and mu(MoK alpha) = 0.598 mm(-1). The final R = 0.0781 and wR = 0.1363 for 1972 observed reflections with I > 2 sigma(I) and R = 0.0897 and wR = 0.1420 for all data. X-ray diffraction reveals that the Phen and p-methy benzoic acid ligand link the Mn atoms into a single one-dimensional coordination polymer, and extensive intermolecular pi-pi interactions lead these 1D chains to form a two-dimensional supramolecular architecture.
