To the best of our knowledge, the only previous reports of any compounds belonging to this family were by Cygańksi, but in these early studies the analysis was confined principally to determining their composition. The following compositions were reported: MnBi(SCN) ] which corresponds to 5 and 6. The fact that these early studies report compositions we have not yet synthesised ourselves indicates that perhaps there is even more latent complexity in this family of materials than we have uncovered.
