The Ruddlesden-Popper phases are one form of these minerals composed of strontium silicate and strontium oxide. These minerals have 8 vertex sharing BX6 octahedra and AX12 cuboctahedra, with the A atoms occupying corners, the B atoms occupying the body centers, and the anions at face centers. Alternating layers of distorted tetrahedral and tilted octahedral characterize the structure of the "oxygen deficient" varieties of these minerals, examples of which include brownmi

Alternating layers of distorted tetrahedral and tilted octahedral characterize the structure of the "oxygen deficient" varieties of these minerals, examples of which include brownmillerite. Many high (*) temperature superconductors are minerals of this type consisting of copper-oxide layers, and a layer of magnesium silicate at the core mantle boundary is thought to exist in the "post" form of these minerals. Examples of these minerals include  For 10 points, identify this family of minerals whose first discovered member was calcium titanate, and are named for some Russian mineralogist.
