From tectons to composite crystals

A combination of the tecton 1(2+) with [M-II(CN)(6)](4-) (M = Fe, Ru) complex anions leads to the formation of analogous two-dimensional (2-D) H-bonded networks and isomorphous crystals. Based on the isomorphous nature of the two crystalline systems, the three-dimensional (3-D) epitaxial growth of composite crystals up to generation three was achieved and visually demonstrated.
