以La 2 O3、CuI和Ina为原料,通过水热反应合成了三维柱撑La(III)-Cu(I)异金属配位聚合物[La 2Cu 4 I3(Hina)7(H2O)]n(1)(Hina =异烟酸).晶体结构通过单晶X射线衍射测定。HCP 1结晶于单斜晶系空间群P21/c,晶胞参数:a = 17.0147(3)Å,B = 18.4431(3)Å,c = 16.7487(3)Å,β = 102.469(2)°,V = 5131.84(15)Å 3,Z = 4。其特征在于3D柱撑层异金属有机框架,其中Ln-ina层由离散的[Cu 8I 6(ina)12]单元沿着a轴方向柱撑。此外,研究了其固态光致发光特性。
A three-dimensional (3D) pillared-layer La(III)-Cu(I) heterometallic coordination polymer (HCP) formulated as [La2Cu4I3(Hina)7(H2O)]n (1) (Hina = isonicotinic acid), is synthesized by a hydrothermal reaction of La2O3, CuI, and ina. The crystal structure is determined by single crystal X-ray diffraction. HCP 1 crystallizes in the monoclinic space group P21/c with unit cell parameters: a = 17.0147(3) Å, b = 18.4431(3) Å, c = 16.7487(3) Å, β = 102.469(2)°, V = 5131.84(15) Å3, Z = 4. It features a 3D pillared-layer heterometallic organic framework, where Ln-ina layers are pillared by discrete [Cu8I6(ina)12] units along the direction of the a axis. In addition, the solid-state photoluminescent property is investigated.
