Abstract:
In the title complex, [PdI(2)(C(24)H(31)N(3))(2)]·2C(6)H(6), the Pd(2+) ion is located on an inversion centre in a slightly distorted square-planar geometry. The angle between the I(2)C(2) square plane and the mean plane of the N-heterocyclic carbene ring is 79.8 (2)°, with I-Pd-C-N torsion angles of -81.1 (6) and -78.2 (5)°. The Pd-carbene and Pd-I distances are 2.016 (6) and 2.5971 (10) Å, respectively.
