✦ Synopsis
p = 33.30 cm I . 2$,,, = 45.0". 9702 reflections collected, 5062 independent (R,,, = 0.0642) and 4629 observed [F,>4a(Fo)]. The structure was solved by direct methods and refined on F2 using SHELXTL software. Data were corrected for Lorentz and polarization effects. No absorption correction was applied. All Ag. Te. and P atoms were refined anisotropically and hydrogen atoms were not included (177 parameters). Final R = 0.0678 and UR, = 0.1899 with GOF =1.077 and an absolute structure parameter = -0.06(7). Largest difference peak and hole =1.62 and -0.94 e k ' , respectively.

The structure was solved and refined as for 1 . A11 non-hydrogen atoms (with the exception of the two solvent molecules) were refined anisotropically and hydrogen atoms were included in calculated positions with refined I Y , ~~ values (1724 parameters) lo yield R = 0.0302 and nR2 = 0.0743 with GOF = 0.922.
