Abstract

Isonitrosobenzoylacetone is particularly interesting, as the isonitroso group has two potentially coordinating sites which can compete with the cabonyl groups in forming bonds with the metal ions. In this paper tris(isonitrosobenzoylacetonato)cobalt(III) and bis(isonitrosobenzoylacetonato)palladium(II) have been prepared, and their structures have been investigated. Spectroscopic studies lead to the conclusion that the both complexes do not contain an OH group in the chelated five-membered ring structure in which the ligand coordinates to metal through oxygen of the acetyl group and nitrogen of the isonitroso group. The coordination manner of this ligand is similar to that of isonitrosobenzoylacetone obtained by Patel and Haldar.

Ambidentate 리간드인 isonitrosobenzoylacetone을 리간드로 하는 금속착물, tris(isonitrosobenzoylacetonato)cobalt(III) 및 bis(isonitrosobenzoylacetonato)palladium(II)을 합성한 후 분광학적 방법에 의하여 이들의 결합구조를 조사하였다. 즉 착물에서 리간드는 아세틸기의 산소 및 이소니트로소의 질소원자를 통하여 금속에 배위되어 5원의 킬레이트고리를 이루고 있음을 알 수 있었다. 이 결합구조는 Patel과 Haldar등이 얻었던 isonitrosoacetylacetone착물의 그 것들과 유사하다.
