摘　　要：合成了N-乙酰皮考林酰肼α-(C_5H_4N)CONHNHCOCH_3(简写为HL及其镍配合物Ni~ⅡL_2·1.5CH_3OH·H_2O(C_(17.5)H_(24)-N_6NiO_(6.5)).配合物晶体属于单斜晶系,空间群为P2_1/c,a=1.5393(l)nm,b=0.80278(7)nm,c=1.8245(l)nm,β=105.985(3)°,V=2.1674(3)nm^3,Z=4,F(000)=1004,R=0.0503.在配合物中,镍(Ⅱ)原子呈扭曲的N_4O_2八面体配位构型,晶体通过分子间氢键作用形成一维的无限链状结构.红外光谱表明,配体在形成配合物后,ν(C=O)和ν(C=N)红移.电子光谱表明存在π-π~*和d-π~*的跃迁.The ligand HL (HL = N-acetylpicoloylhydrazide, alpha-(C5H4N) CONHNHCOCH3) and its nickel complex NiL2.1.5H(2)O (C17.5H24N6NiO6.5) have been synthesized. Crystal data: space group P2(1)/c, a = 1.5393(1) nm, b = 0.80278(7) nm, c = 1.8245(1) run, beta = 105.985(3)degrees, V = 2.174(3) nm(3), Z = 4, F(000) = 1004, R = 0.0503 for 2799 observed reflections [I greater than or equal to 2sigma (1)]. The nickel atom in the complex is of irregular polyhedral N4O2 coordination. There is a one-dimensional chain structure through the intermolecular hydrogen bonds. The nu( C = 0) and nu(C = N) bands display a shift to lower frequencies in IR spectra. There are pi-pi* transition and d-pi* charge-transfer transition in electronic spectra.
