The result shows that the complex crystallizes in monoclinic, space group P21 / c with a=0.695 7(4) nm, b=0.988 7(4) nm, c=1.974 8(7) nm, β=91.934(19)°, V=1.357 5(10) nm3, Z=4, Dcalc=1.831 g·cm-3, F(000)=752, μ=1.50 cm-1, the final R=0.036 6, wR=0.091 0. The coordination environment of Ag髣 is nearly linear with two N atoms, and each L ligand links two Ag髣 atoms using its two imidazolyl N atoms to generate an infinite one-dimensional (1D) chain structure. The 1D chains are further connected by C-H.O hydrogen bonds to give a three-dimensional structure. CCDC: 609514.展开更多
A trinuclear Zn(II) complex Zn3(L)2(Cl)2(OSO3)2(H2O)2·2H2O (1) (L=N1-(2-aminoethyl)-N1-(2-imidazolethyl)-ethane-1,2-diamine) was synthesized by reaction of ligand L with ZnSO4·7H2O at pH=9 in air. The comple...A trinuclear Zn(II) complex Zn3(L)2(Cl)2(OSO3)2(H2O)2·2H2O (1) (L=N1-(2-aminoethyl)-N1-(2-imidazolethyl)-ethane-1,2-diamine) was synthesized by reaction of ligand L with ZnSO4·7H2O at pH=9 in air. The complex has been characterized by elemental analysis, FTIR and X-ray single crystal diffraction. It reveals that the crystal of complex 1 belongs to monoclinic C2/c space group, a=3.516 9(7) nm, b=0.676 57(14) nm, c=1.502 2(3) nm, β=110.955(4)°, V=3.337 9(12) nm3, Z=4. In complex 1, two ligands L bridge three Zn(II) centers to form trinuclear structure which was further connected by hydrogen bonding to form two-dimensional structure. CCDC: 609515.展开更多
