摘要：

Reaction of Zn(AcO)(2).2H(2)O with 6-methyl-2-pyridinecarboxylic acid (L) yielded a new compound [Zn(MeC5H3NCOO)(2)(H2O)].H2O. This complex was characterised by elemental analyses, conductivity measurements, infrared, H-1 and C-13{H-1} NMR spectroscopies and single-crystal X-ray diffraction. The crystal structure consists of discrete molecules involving a pentacoordinated Zn atom with a geometry intermediate between a trigonal bipyramid and a square pyramid and with the two N-py atoms occupying the apical sites. Treatment of the complex [Zn(MeC5H3NCOO)(2)(H2O)].H2O with 2,2'-bipyridine (bpy) produced [Zn(MeC5H3NCOO)(2)(bpy)]. The metallic atom in this complex displays a distorted octahedral geometry and is coordinated to two ligands (L) via the pyridine nitrogen and the carbonyl oxygen atoms and to one 2,2'-bypyridine (bpy).
