The two‐dimensional network topology of the mixed alkali title compound, K 1.33 Na 0.67 Si 2 O 5 , is found to differ from that of the end‐member compositions, Na 2 Si 2 O 5 and K 2 Si 2 O 5 . The network of the silicate sheet consists of rings with four, six and eight SiO 4 tetrahedra. The cations are sandwiched between the silicate sheets.
