Given the formula, the sulfate probably occupies the $1$ $1$ coordination site on the octahedral cobalt centre.

Explanation:

Given this formulation, the parent complex ion is likely, ${[C o {(N H_{3})}_{5} (O S O_{3})]}_{5}^{+}$ $[Co(NH_3)_5(OSO_3)]^+$ , in which the sulfato ligand acts as a unidentate donor towards the octahedral $C o (I I I)$ $Co(III)$ centre. I don't know the lingo with respect to secondary and primary valences.
