A nonanuclear Cu4ⅡTi5Ⅳ heterometallic cluster,[Ti5 Cu4 O6（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 hetero metallic co re.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.
