Homework Help: Coordination Number

  1. Sep 18, 2008 #1
    Can any body please tell me if there's a way to determine the coordination number of a cation in relation to an anion just from the chemical equation (without atomic radii, tables, etc.)? For example, the C.N. of Ca2+, Al3+ and Si4+ in Ca3Al2Si3O12 (grossular garnet).

    I'm pretty certain that you need to know the structure for this one.
