ReAs2Cl crystallizes in the monoclinic Cm space group. Re(1) is bonded in a 10-coordinate geometry to two equivalent Re(1) and eight equivalent As(1) atoms. Both Re(1)-Re(1) bond lengths are 2.80 Å. There are a spread of Re(1)-As(1) bond distances ranging from 2.65-3.07 Å. As(1) is bonded in a 9-coordinate geometry to four equivalent Re(1), two equivalent As(1), and three equivalent Cl(1) atoms. Both As(1)-As(1) bond lengths are 2.80 Å. There are a spread of As(1)-Cl(1) bond distances ranging from 2.65-2.93 Å. Cl(1) is bonded in a 4-coordinate geometry to six equivalent As(1) atoms.
