What angle is made by the lines connecting any Zn2+ to any two of its nearest neighbours? — Solid State Chemistry Question

💡 Solution & Explanation

The coordination of Zn2+ is tetrahedral, so the angle between the lines connecting the Zn2+ ion to any two of its nearest neighbours ($S_2$- ions) is the tetrahedral bond angle, which is 109\u00b0 28'.
