The structure of tris thiourea copper 1 sulphate is [Cu(thiourea)3]SO4. It consists of a central copper(II) ion coordinated by three thiourea molecules and one sulphate ion. The copper(II) ion is in a distorted octahedral environment, with the thiourea molecules occupying the equatorial positions and the sulphate ion occupying one of the axial positions. The other axial position is occupied by a water molecule. The thiourea molecules are coordinated to the copper(II) ion through the sulphur atoms of the thiourea groups. The sulphate ion is coordinated to the copper(II) ion through the oxygen atoms of the sulphate group.
