Is there an explanation for what we see? Are prolonged blobs with a single “core” p-orbitals? What are core and non-core parts at all? If it’s a regular crystal

Is there an explanation for what we see? Are prolonged blobs with a single “core” p-orbitals? What are core and non-core parts at all? If it’s a regular crystal with a non-homogeneous lattice, why its formula is so simple and has no dots in it? The image repeats [2-core, 1-core, blob, blob], and that’s PrScO3, seems related, but which elements are placed where?
