摘要: The synthesis of a new bifunctional ligand, 4-methyl-2,6-bis(pyrazol-1-ylmethyl)phenol (HL), and the structures its complexes with zinc(II) are described. ligand reacts zinc chloride to form macromolecular complex, [{Zn(HL)Cl2}n]1. In basic solution two binuclear complexes, [Zn2L2Cl22, [Zn2(µ-OH)LCl2]3, formed under different reaction conditions. molecular 1 2 have been characterized by X-ray diffraction: 1, monoclinic, space group =P21/c, Z= 4, a= 12.357(2), b= 12.400(2), c= 14.957(4)A, β= 100.18(2)°; 2, triclinic, =P, 9.194(1), 10.040(1), 10.316(2)A, α= 114.40(2), 115.93(2), γ= 89.16(1)°. co-ordination sphare in complex is tetrahedral, it distorted square pyramidal.
