ANhydrous Copper Sulphate

i really wish we all go through this very well,while i was doing my chemistry lab,me and my classmates decided to go over this ,while we were doing this we found out that there is something we called anhydrous copper 11 tetraoxosulphate v1 we tried as hard as possible to get to the route of the matter but we  couldnt. but i will try and get enough evidence.we did not know how it gt there but we will surely get to the route of this matter.
