Chloro[N,N'-ethylenediiminobis(acetylacetonato)]gallium(III).

In the title compound, [Ga(C12H18N2O2)Cl], the Ga atom is coordinated to a Cl atom and the two imine N and two enolate O atoms of the Schiff base ligand. The literature reveals few examples of a five-coordinate GaO2N2Cl environment, and only two where both the N and the O atoms are contained within the same ligand. This configuration has the effect of constraining the complex into a square-pyramidal geometry with less distortion than if formed by two or more ligands. The Ga-N and Ga-O distances are within the ranges expected for Ga-Schiff base derivatives. This compound is also the first group 13 complex containing the N,N'-ethylenebis(acetylacetoneimine) (acacen) ligand.
