{[Cu_3(cis-DAM)_4(OH)_2]·12H_2O}_n 1 and [Ag_3(trans-DAM)_2(NO_3)]_n 2 with a flexible ligand N,N?-diacetic acid imidazolium(HDAM) were synthesized and characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in the orthorhombic I222 space group with a = 12.033(2),b = 12.498(3),c = 14.963(3) ?,V = 2250.4(8) ?~3,Z = 8,C_7H_(13.5)N_2O_(7.5)Cu_(0.75),M_r = 293.35,D_c = 1.732 g·cm~(-3),F(000) = 1210,GOF = 1.087,the final R(I > 2σ(I)) = 0.0521 and w R(all data) = 0.1386. Compound 2 crystallizes in the monoclinic C2/c space group with a = 21.601(4),b = 8.321(2),c = 13.589(3) ?,β = 126.95(3)°,V = 1951.9(7) ?~3,Z = 8,C_7H_7N_(2.5)O_(5.5)Ag_(1.5),M_r = 375.96,D_c = 2.559 g·cm~(-3),F(000) = 1448,GOF = 1.017,R(I > 2σ(I)) = 0.0222 and w R(all data) = 0.0633. Compound 1 displays a novel 2D layer,consisting of a couple of left-helical chains with a pitch of 12.498(3) ? formed by μ_3-cis-DAM~– ligands and Cu(1) ions,which are stabilized by hydrogen bonding interactions to give a 3D supramolecular framework. As for 2,Ag(1) ions are doubly bridged by trans-DAM~– and NO_3~– to form [Ag(1)_2O_4] chains,which are further connected by Ag(2) and trans-DAM~– to build a 3D framework. Additionally,thermogravimetric analyses,FT-IR spectroscopy,UV-visible spectroscopy,and the fluorescent properties were discussed.
