摘要：

Urotropinium triiodide C6H13N4I3 is formed by the reaction of equimolar amounts of urotropinium iodide and iodine in (t)BuOH as red-brown cube-like crystals melting at 402 K under decomposition. The compound crystallizes monoclinically in the space group P2(1)/c with a = 952.0(3) pm, b = 1160.2(6) pm, c = 1149.9(4) pm, beta = 92.22(3)-degrees and Z = 4. The till now not described crystal structure (R = 0.027 for 1860 observed reflexes) contains urotropinium ions UrH+ and slightly distorted triiodide ions I3-(d(I-I) = 292.3(1), 294.1(1) pm, phi(I-I-I) = 178.27(2)-degrees which are linked to ion pairs by a rather short contact (d(I...I) = 389.0(1) pm, phi(I-I...I) = 149.12(2)-degrees).
