Abstract
The structure of (C4H9NH3)(2)SnCl6 is orthorhombic, M(m) = 479.68, Pnm a, a = 12.242(3)Angstrom, b = 7.329(3)Angstrom, c = 21.527(4)Angstrom, Z = 4, V = 1931.4(11)Angstrom(3), D = 1650 mg/m(3), lambda = 0.71069 Angstrom, T = 293(2) K, R = 0.044 for 1900 reflections with I > 2 sigm a(I). The structure is characterized by ionic layers sandwiched betwee n layers of paraffinic chains. A structural phase transition is detect ed by means of differential scanning calorimetry. The basic thermodyna mic data are determined for this transition. The Raman and infrared sp ectra at room temperature are recorded and some frequencies are assign ed.
