Preparation and crystal structure of dual-functional precursor complex bis(acetylacetonato)nickel(II) with 4-pyridyltetrathiafulvalene.

A tetrathiafulvalene (TTF) derivative 4-pyridyltetrathiafulvalene (Py-TTF) was synthesized. The 1:2 Ni complex 1 of bis(acetylacetonato)nickel(II) coordinated with Py-TTF was prepared. Complex 1 crystallizes in the monoclinic space group P2(1)/c. Two pyridyl N atoms from two different molecules of Py-TTF are coordinated in the trans configuration to the Ni ion of Ni(acac)2 to form an octahedral Ni complex, which is a precursor for both conducting and magnetic materials.
