[C(6)H(5)NH(CH(3))(2)](2)Te(2)I(10): secondary I...I bonds build up a 3D network.

The crystal structure of [C(6)H(5)NH(CH(3))(2)](2)Te(2)I(10) consists of the N,N-dimethylanilinium cation and a hitherto unreported tellurium iodide anion Te(2)I(10)(2)(-) [crystal data: C(8)H(12)NTeI(5), monoclinic, P2(1)/c, a = 9.4787(2) A, b = 14.2874(3) A, c = 13.6869(3) A, beta = 95.1918(8) degrees, V = 1845.96(7) A(3), Z = 4]. The Te(2)I(10)(2)(-) dianion is based on two edge-sharing TeI(6)(2)(-) octahedra, and interestingly, it builds up a three-dimensional Te(IV)-I open framework through extensive interconnecting I.I contacts. These I.I contacts (3.66-3.80 A) are significantly shorter than the corresponding sum of van der Waals radii (4.0 A) and may potentially promote charge carrier migration throughout the Te-I network. This material can also be drop-cast into thin films from a heated DMF solution.
