3D coordination polymers with N-heterocyclic Ga(I) moieties

Abstract

The reactions of bimetallic acenaphthene-1,2-diimine complex [(Dpp-bian-GaCr(CO)5]2- [Na(Thf)2]2(I) (Dpp-bian = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) with 4,4ʹ-bipyridine (4,4ʹ-Bipy) and 1,3-bis(4-pyridyl)propane (Bpp) in THF gave 3D coordination polymers [{(Dppbian) GaCr(CO)5}{Na(4,4ʹ-Bipy)3}]n(II) and [(Dpp-bian)GaCr(CO)4Na(Et2O)(Bpp)1,5]n(III), respectively. Compounds II and III were characterized by elemental analysis and NMR and IR spectroscopy. The molecular structure of IIwas established by X-ray diffraction (CCDC no. 2278024).
