摘要：

Dipyridyl-functionalized salan ligand (H2L) was synthesized to construct a mono- nuclear Cu(salan) complex, [CuL(CH3CN)2(H2O)6] (1), through diffusion method. 1 was characterized by IR, microanalysis, TGA and single-crystal X-ray crystallography. It crystallizes in orthorhombic space group P21212 with a = 17.6640(16), b = 18.6750(16), c = 16.0625(14) , V = 5298.6(8) 3 , Z = 4, M r = 994.70, D c = 1.247 g/cm 3 , F(000) = 2116, μ = 0.469 mm -1 , GOOF = 1.073, the final R = 0.0499 and wR = 0.1395 for 11816 observed reflections with I > 2σ(I). In the title compound, the basic building unit consists of two mononuclear Cu(salan) which orient in opposite directions and are locked together via weak intermolecular C-H···π interactions. The adjacent building units are further directed into a 2D supramolecular network structure via H bonds, between which reside the guest acetonitrile and water molecules. In addition, the presence of exposed NH-functionalities and coordination unsaturated Cu centers in 1 provide a great chance to recognize tartaric acids through CD titration in solution.
