One novel neodymium-tartrate complex exhibiting distinctive rare topology,name-ly,[Nd(TTA)1.5(H2O)]·H2O(1,H2TTA = tartaric acid),was successfully synthesized by the reaction of neodymium-oxide with H2TTA under hydrothermal conditions.Single-crystal X-ray diffraction analysis reveals that 1 belongs to the monoclinic system,space group P21/c with a = 6.0357(13),b = 7.6106(17),c = 24.389(5) ,β = 100.136(5)°,V = 1102.8(4) 3,Z = 4,Dc = 2.423 g·cm-3,μ = 4.763 mm-1,F(000) = 776,the final R = 0.0689 and wR = 0.2191.In complex 1,the 2D layer consisting of μ4-ligands and 4-connected Nd(III) centers is a rare example of uni-nodal net of(42.64) topology.The 2D layers are further connected by μ2-TTA2-ligands to give a 3D(42.64)(42.67.8) topological structure,where the Nd(III) atoms act as rare 5-connected topological blocks.

One novel neodymium-tartrate complex exhibiting distinctive rare topology, name-ly, [Nd (TTA) 1.5 (H2O)]. H2O (1, H2TTA = tartaric acid), was synthesized synthesized by the reaction of neodymium-oxide with H2TTA under hydrothermal conditions.Single-crystal X-ray diffraction analysis reveals that 1 belongs to the monoclinic system, space group P21 / c with a = 6.0357 (13), b = 7.6106 (17), c = 24.389 (5) °, V = 1102.8 (4) 3, Z = 4, Dc = 2.423 g · cm -3, μ = 4.763 mm -1, F (000) = 776, the final R = 0.0689 and wR = 0.2191 .In complex 1, the 2D layer consisting of μ4-ligands and 4-connected Nd (III) centers is a rare example of uni-nodal net of (42.64) topology.The 2D layers are further connected by μ2-TTA2-ligands to give a 3D (42.64) (42.67.8) topological structure, where the Nd (III) atoms act as rare 5-connected topological blocks.
