摘　　要：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 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.
