Re2O3Cl7 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two Re2O3Cl7 clusters. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one Cl(2), one Cl(3), one Cl(4), and one Cl(7) atom. In the second Re site, Re(2) is bonded in a 6-coordinate geometry to one O(1), one O(3), one Cl(5), one Cl(6), and two equivalent Cl(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Re(1) and one Re(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Re(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Re(2) atom. There are seven inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a water-like geometry to two equivalent Re(2) atoms. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Re(1) atom. In the third Cl site, Cl(3) is bonded in a single-bond geometry to one Re(1) atom. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one Re(1) atom. In the fifth Cl site, Cl(5) is bonded in a single-bond geometry to one Re(2) atom. In the sixth Cl site, Cl(6) is bonded in a single-bond geometry to one Re(2) atom. In the seventh Cl site, Cl(7) is bonded in a single-bond geometry to one Re(1) atom.
