A novel manganese complex with mixed ligands: preparation, structure, photoluminescent and semiconductive properties. (1st March 2018) - Xu, Ya-Ping
A manganese complex with mixed ligands, [Mn(2, 2'-biim)2(4, 4'-bipy)]n[Mn(2, 2'-biim)3]2n6n(ClO4)·8nH2O (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.
