The title compound, [N(C 2 H 4 OH) 2 H 2 ][Cr 7 NiF 8 (C 5 H 9 O 2 ) 16 ]·0.5C 4 H 8 O 2 , is a heterometallic wheel templated by a protonated amino alcohol. It consists of an octagon of metal centres, with each edge of the octagon bridged by a single F − anion and two carboxylate groups. Each metal atom is octahedrally coordinated. The protonated amine molecule protrudes through the cavity of the ring, while a solvent ethyl acetate molecule fills up the vacant space between the ring anions. It appears that the one equivalent of Ni atoms is unevenly distributed among the eight metal sites.
