A manganese complex with mixed ligands, [Mn(2,2'-biim)(2)(4,4'-bipy)](n)[Mn(2,2'-biim)(3)](2n)6n(ClO4) center dot 8nH(2)O (2,2'-biim = 2,2'-biimidazole; 4,4'bipy = 4,4'-bipyridine), has been obtained by a hydrothermal procedure and its structure determined by single-crystal X-ray crystallography. A two-dimensional (2-D) supramolecular layer is established through hydrogen-bonding interactions. Solid-state photoluminescence measurement reveals that this complex shows a blue light emission. Solid-state diffuse reflectance determination uncovers the presence of a narrow optical band gap of 2.18 eV in this complex.
