| Abstract: | A nonanuclear Cu4IITi5IV heterometallic cluster,[Ti5Cu4O6(ba)16] (1, Hba=benzoic acid) was synthesized in one-pot reaction under the solvothermal condition. The metallic skeleton 1 contains a Ti5 core constructed from two vertex-shared Ti3 triangles and four separated Cu atoms outside which are connected together by μ3-O2- ions. Total 16 ba- ligands adopt μ2-η1:η1 coordination mode to protect the overall heterometallic core. Due to the unique d-d transitions of CuII ion, the reflectance spectrum of 1 displays broad and strong absorption towards visible light extending to the near-infrared region. Moreover, 1 shows almost purely paramagnetic behavior with the presence of weak antiferromagnetic interactions at low temperatures. |
