Abstract

The crystal structures of the title compounds, [Bi(S2CNEt2)l2(bipy)], (1), and [Bi(S2CNEt2)l2(terpy)], (2) (bipy = 2,2′-bipyridyl, terpy = 2,2′:6′,2″-terpyridyl), have been determined by single-crystal X-ray diffraction methods at 295(1) K and refined by least-squares procedures to conventional residuals of 0.047 and 0.045 respectively for 2 794 and 1 589 'observed' reflections. Crystals of (1) are triclinic, space group P1, with a = 13.432(5), b = 10.122(4), c = 9.780(5) Å, α = 117.66(3), β = 98.89(4), γ = 100.42(3)°, and Z = 2. Crystals of (2) are monoclinic, space group P21/c, with a = 9.122(4), b = 11.440(6), c = 24.684(9) Å, β = 94.21(3)°, and Z = 4. The molecule of (2) is pseudopentagonal bipyramidal in its co-ordination, the two iodine atoms lying axial [Bi-l, 3.070(2), 3.031 (2) Å; l-Bi-l, 169.0(1)°]. In (1), a binuclear complex is formed, [(bipy)l(Et2NCS2)Bil2Bi(S2CNEt 2)l(bipy)], with a pair of bridging iodine atoms.
