摘要

Two new heterocyclic ligands, 2, 6-bis-(2′-hydroxyphenyl) pyridine 2 and 3, 5-bis-(2′- hydroxyphenyl) pyrazole 4 have been prepared. The molecular structures of 2, 6-bis-(2′- methoxyphenyl) pyridine 1, the tetrafluoroborate salt of 2, 6-bis-(2′-hydroxyphenyl) pyridine 3 (a monohydrate) and that of compound 4 have been determined by X-Ray analysis. In 1, the phenyl rings are oriented so that the oxygen atoms of the methoxy groups are placed ...
