Yes it is possible that it can be Manganese (II) Phosphate.
No. of Manganese ion = 8 + 1 = 9
No. of phosphate ion = 6
Charge on Manganese ion = +2
Charge on phosphate ion = -3
clearly, product of charge and no. of ions are equal i.e, 18
Thus each lattice is neutral in charge.

Question 61 [6 marks] (a) In the crystal structure of sphalerite (ZnS), the sulfur anions (S2) adopt a face-centred cubic arrangement. Using the cubic framework shown below, draw the anion locations in a face-centred cubic unit cell. (Represent each ion as a small solid circle). For the face-centred cubic unit cell you have drawn in (a), how many sulfur anions (b) make a contribution to the unit cell? What is the sulfur anion content of the face-centred cubic unit cell...

2. The CsCl structure has a cubic unit cell that contains Clanions at the corners and a Cs* cation in the center. This unit cell is commonly, and mistakenly refered to as "body-centered cubic". Why is it not body-centered cubic. A. Actually, this is not a mistake. It is body-centered cubic B. Because the cations must be on the corners and anion in the center in order to be called body centered cubic. This arrangement is anti-body-centered cubic. C. Because...
