文摘

Reactions of perchlorates of iron(II), nickel(II), and zinc(II) with 2,2':6',2' ':6' ',2' ''-quaterpyridine (qtpy) gave the firstcrystallographically established bis-qtpy metal complexes of formula [M(qtpy)₂][ClO₄]₂ (M = Fe, Ni, Zn). Coordinationof two terdentate quaterpyridines to the same center produces a distorted octahedron of six nitrogen atoms aroundthe metal, leaving two pendant pyridyl groups, one for each quaterpyridine. For the diamagnetic zinc system, anNMR investigation has been carried out in order to establish the conditions to obtain the intermediate mono-qtpycomplex, of formula [Zn(qtpy)(H₂O)₂][ClO₄]₂, which has also been crystallographically established. The correspondinghexafluorophosphate derivatives [M(qtpy)₂][PF₆]₂ (M = Ni and Zn) were prepared in DMF at room temperature.
