• Crystallographic data for 14: C25H31BrN4O4P2S2, M = 657.51 g mol−1, monoclinic system, space group P2(1)/c, a = 8.632(2), b = 29.008(6), c = 11.634(2) Å, β = 90.35°, V = 2913.1(10) Å3, Z = 4, D c = 1.499 g cm−3, F(000) = 1352, crystal dimensions of 0.30 mm × 0.40 mm × 0.40 mm. Data were measured at 293 K on Enraf-Nonius CAD4 diffractometer with graphite crystal monochromated Mo Kα radiation (λ = 0.71073 Å). The structure of the crystal was solved by the direct methods (SHELXS-86) and anisotropically refined by full-matrix least-squares on F 2 to final R = 0.0510 and R w = 0.1423 with w = 1/[σ2(F 0 2) + (0.1333P)2 + 0.0000P] where P = (F 0 2 + 2Fc 2)/3 using 4991 independent reflections (2.24∘≤θ≤24.97∘). Corrections for Lp factors and empirical absorption type based on PSI-scan technique were applied to the intensity data. Most of the non-hydrogen atoms were located from an E-map. The others were determined with successive difference Fourier syntheses. The hydrogen atoms were added theoretically from a Fourier map and from expected geometry. All calculations were performed on a PDP 11/44 computer using SDP-PLUS program system
