The incommensurate composite systems M<Subscript>14</Subscript>Cu<Subscript>24</Subscript>O<Subscript>41</Subsc ript> (M=Ca, Sr, La) are based on two fundamental structural units: CuO<Subscript>2</Subscript> chains and Cu<Subscript>2</Subscript>O<Subscript>3</Subscript> ladders. We present electronic structure calculations within density functional theory in order to address the interrelations between chains and ladders.
