A chiral 3D metal-organic framework [CdL]·DMSO·H2O(1) was constructed by an N-methyl substituted salan ligand(H2L), and characterized by elemental analyses, IR, TGA, powder XRD and single-crystal X-ray crystallography. 1 crystallizes in the chiral hexagonal space group P6522 with a = b = 12.2175(3), c = 51.450(3) , V = 6650.9(4) 3, Z = 6, Mr = 883.45, Dc = 1.323 g·cm–3, F(000) = 2760, λ(CuKα) = 1.54178 , μ = 4.771 mm–1, GOOF = 1.041, R = 0.0313 for 3901 observed reflections with I > 2σ(I) and wR = 0.0773. 1 consists of three identical sets of independent 3D frameworks interpenetrated with each other. In each set of such 3D frameworks, one half of the monomer(CdL)1/2 as the building unit forms double antiparrel helical chains which are further bridged together by other(CdL)1/2 units from adjacent helical chains. All CdL units in 1 adopt Δ geometry. DMSO and water guest molecules are found in the gap of the interpenetrated frameworks.
