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.

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 CH ··· 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 unsatura ted Cu centers in 1 provide a great chance to recognize tartaric acids through CD titration in solution.
