由吡啶-2-醛和2-氨基苯酚及其两种甲氧羰基衍生物形成的三齿Schiff碱配体HL 1、HL 2和HL 3与AgNO 3、[Cu(CH 3CN)4] PF 6、Cu(NO 3)2、Co(NO 3)2和Zn(NO 3)2反应,得到下列配合物:[Ag(HL)2] NO 3;(1a,2a,3a); [CuII(HL)L] PF 6(1b,2b,3b); [CuII(HL)L]NO3(1c,2c,3c);和[M(HL)L]2[M(NO3)4],其中MCo(II)(1d,2d,3d);或Zn(II)(1 e,2 e,3e),其原则上限定了某些金属栅中金属位点的基本特性。配合物的特征在于通过光谱技术和元素分析。通过X射线单晶衍射确定了配合物2b和2 e的固态结构。
Reactions of the tridentate Schiff-base ligands HL1, HL2and HL3formed from pyridine-2-aldehyde and 2-aminophenol plus two of its methoxycarbonyl derivatives, with AgNO3, [Cu(CH3CN)4]PF6, Cu(NO3)2, Co(NO3)2and Zn(NO3)2give complexes of the following types: [Ag(HL)2]NO3; (1a, 2a, 3a); [CuII(HL)L]PF6(1b, 2b, 3b); [CuII(HL)L]NO3(1c, 2c, 3c); and [M(HL)L]2[M(NO3)4] where MCo(II) (1d, 2d, 3d); or Zn(II) (1e, 2e, 3e), which in principle define the basic characteristics of the metal sites in certain metallogrids. The complexes have been characterized by spectroscopic techniques and elemental analysis. The solid state structures of complexes 2b and 2e have been established by X-ray crystallography.
