Abstract
The perovskite structure type was early recognized as the structural a ncestor of high-T-c superconductors. The similarity with Aurivillius p hases was also noticed for the Bi-Sr-Cu-O superconductors since the fi rst structural studies. An even closer analogy with Sillen phases is n ow pointed out, and the basic principles of a unified crystal chemical systematics of oxide superconductors is presented. Structural represe ntations through condensed models are also briefly described.
