Intermolecular interactions in the structure of new molecular semiconductor [Pd(dddt)2]2CF3SO3

An X-ray structural investigation of a new molecular semiconductor, [Pd(dddt)2]2CF3SO3 (1), where dddt2− is 5,6-dihydro-1,4-dithiin-2,3-dithiolate, is made. Crystal data of 1:a = 6.521(7) Å, b = 8.354(4) Å, c = 16.113(6) Å, α = 87.12(4)°, β = 85.51(6)°, γ = 67.94(7)°, V = 811(1) Å3, triclinic, space group P. Crystal structure 1 is characterized by layers of [Pd(dddt)2]1/2+ radical cations, with [CF3SO3]− anions located between them. In these layers, [Pd(dddt)2]1/2+ cations form dimers with strongly shortened intermolecular contacts Pd…Pd 3.031 (2) Å. The [CF3SO3]− anion in the structure of 1 is disordered.
