Melilites ([A2]2[BI]2[BII2O7]2) are layered oxides containing distorted pentagonal rings, constructed from BO4 tetrahedra, whose basic structure can be ‘modulated’ to accommodate misfit between the interlayer spacing and the bridging A cations. While prototypically regarded as possessing a tetragona...
