Compounds may have at least two structural units, which may be referred to as ligands. Each structural unit includes at least one spacer group and two or more donor groups. Compounds may have two or more iron(III) cations, one or more of which may be a high- spin iron(III) cation or high-spin iron(III) cations, two or more gallium(III) cations, or at least one iron(III) cation, one or more of which may be a high-spin iron(III) cation or high-spin iron(III) cations, and at least one gallium(III) cation, where the iron(III) cation(s) and/or the gallium(III) cation(s) coordinate to the donor groups. The compounds may be self-assembled cages. A composition may include one or more of the compound(s) and a pharmaceutically accepted carrier. Methods of imaging use one or more of the compound(s) and/or one or more of the composition(s).
