The new compound Cs10P8Se20 features the heterotetracyclic [P3Se7](3-) anion, a phosphorus-rich four-membered-ring species that possesses a P-P-P unit and formally P3+ and P4+ centers. It crystallizes in the orthorhombic space group Pnnm with a = 26.5456(7) angstrom, b = 8.0254(2) angstrom, c = 11.9031(4) angstrom, and Z = 2 at 100(2) K. The cyclic anion is cocrystallized with a [P2Se6](4-) anion. Electronic absorption, Raman, Fourier transform infrared, and solid-state P-31 NMR spectroscopy studies of Cs10P8Se20 are reported.
