N2 - The crystal and molecular structure of bis(tetraphenylarsonium) bis(maleonitriledithiolato)tellurate(II), a new tellurium(II) compound containing dithiolene ligands, and the single-crystal e.s.r. spectra of the system [AsPh4]2[63Cu/Te(mnt)2] are reported. [AsPh4]2[Te(mnt)2] crystallises in the triclinic space group P1, with a = 10.211 (2), b = 14.460(2) Å, c = 18.583(3) Å, α = 105.95(2), β = 95.60(2), γ = 77.67(2)°, and Z = 2; R = 0.047 for 7 749 observed reflections. The tellurium atoms have trapezoid planar co-ordination with Te-S bond distances of 2.501(1), 2.482(2), 2.971(2), and 3.104(2) Å. In the single-crystal e.s.r. spectra the signals of two Cu sites with somewhat different spin-Hamiltonian parameter sets are observed. The ḡ and the 63Cu hyperfine tensors are rhombic symmetric. The planar [Cu(mnt)2]2- anions are considerably distorted but do not adopt the structure of the tellurium host.
