It is CO2(HPO4)3
Cobalt (II) means Co has a positive charge of 2. However, phosphide has a negative charge of 3. In order to form the compound both charges must be balanced, so you would need 3 Co and 2 P. Cobalt (II) phosphide is Co3P2.
Co+2 PO4-3 <--- these are the ions and their formulas
Co+2 Co+2 Co+2 PO4-3 PO4-3 <---- the charges have to add up to zero, so three +2 cobalt ions cancel out two -3 phosphate ions
Co3(PO4)2 <---- simplify
