RhSe2Cl7 is beta Polonium structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two chloro selenohypochlorite;trichlororhodium molecules. Rh(1) is bonded to one Se(1), one Se(2), one Cl(1), one Cl(7), and two equivalent Cl(6) atoms to form edge-sharing RhSe2Cl4 octahedra. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a trigonal non-coplanar geometry to one Rh(1), one Cl(4), and one Cl(5) atom. In the second Se site, Se(2) is bonded in a 5-coordinate geometry to one Rh(1), one Cl(1), one Cl(2), one Cl(3), and one Cl(7) atom. There are seven inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted single-bond geometry to one Rh(1) and one Se(2) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Se(2) atom. In the third Cl site, Cl(3) is bonded in a single-bond geometry to one Se(2) atom. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one Se(1) atom. In the fifth Cl site, Cl(5) is bonded in a single-bond geometry to one Se(1) atom. In the sixth Cl site, Cl(6) is bonded in a water-like geometry to two equivalent Rh(1) atoms. In the seventh Cl site, Cl(7) is bonded in a distorted single-bond geometry to one Rh(1) and one Se(2) atom.
