Figure 5
Projections of the structure of K3NdSi7O17 along [001] showing the coordination polyhedra about potassium ions. O atoms involved in forming shared polyhedral edges or faces are labeled. (a) Projection from z = −0.5 to z = 0.5, showing polyhedra about K(2); (b) projection from z = 0.1 to z = 0.9, showing polyhedra about K(1). Si and Nd atoms, and those O atoms not bonded to K, have been omitted for clarity.
