Three Mn(II) coordination supramolecules Mn(2,5-dcp)2(H2O)2 (1), Mn(INA)2(H2O)4 (2) and Mn(phen)2Cl2 (3) were synthesized by hydrothermal method (2,5-dcp＝pyridine-2,5-dicarboxylic acid, INA＝ iso-nicotinic acid, phen＝1,10-phenanthroline). The crystal structures of the complexes were determined by X-ray single crystal diffraction, and the complexes were characterized by IR, UV-Vis and surface photovoltage spectrum (SPS). The existence of hydrogen bonds makes the complexes further connect to a 3D infinite net structure. The results of surface photovoltage spec-tra for the complexes 1～3 indicate that the complexes exhibit positive surface photovolt-age responses in the range of 300～600 nm, and possess the characteristic of p-type semiconductor. The ar-ticle discussed the action of hydrogen bonds in the construction of the supramolecules and the change on the surface photovoltage of complexes in the different coordination environments.
