Abstract

K₁₀Sn₃(P₂Se₆)₄ and Cs₂SnP₂Se₆ stabilize the lower oxidation state of Sn²⁺. K₁₀Sn₃(P₂Se ₆)₄ crystallizes in the trigonal space group R3̄ with a = b = 24.1184(7) Å and c = 7.6482(2) Å at 100 K. Cs ₂SnP₂Se₆ crystallizes in P2₁/c with a = 10.1160(4) Å, b = 12.7867(5) Å, c = 11.0828(5) Å, and β = 94.463(3)° at 100(2) K. Electronic absorption spectra revealed band gaps of 1.82 eV for K₁₀Sn₃(P₂Se ₆)₄ and 2.06 eV for Cs₂SnP₂Se ₆. Solid-state magic-angle-spinning ³¹P NMR, UV-vis, Raman, and IR spectroscopy and thermal analysis studies of the compounds are reported.
