Stabilization of Sn2+ in K10Sn3(P2Se6)(4) and Cs2SnP2Se6 Derived from a Basic Flux
K10Sn3(P2Se6)(2) and Cs2SnP2Se6 stabilize the lower oxidation state of Sn2+. K10Sn3(P2Se6)(4) crystallizes in the trigonal space group R (3) over bar with a = b = 24.1184(7) angstrom and c = 7.6482(2) angstrom at 100 K. Cs2SnP2Se6 crystallizes in P2./c with a = 10.1160(4) angstrom, b = 12.7867(5) angstrom, c = 11.0828(5) angstrom, and beta = 94.463(3)degrees at 100(2) K. Electronic absorption spectra revealed band gaps of 1.82 eV for K10Sn3(P2Se6)4 and 2.06 eV for Cs2SnP2Se6. Solid-state magic-angle-spinning P-31 NMR, UV-vis, Raman, and IR spectroscopy and thermal analysis studies of the compounds are reported.
