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) ?, b = 18.4431(3) ?, c = 16.7487(3) ?, β = 102.469(2)°, V = 5131.84(15) ?3, 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.
