| Abstract: 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. |
