Resumo

Abstract The preparation and structures of 2, 2′‐dihydroxyazobenzenato‐dibutyl‐tin [Bu 2 SnL] and 2, 2′‐dihydroxyazobenzenato‐dimethyl‐tin [Me 2 SnL] are described. The complexes were characterized by IR, NMR ( 1 H, 13 C, 119 Sn) and UV/VIS spectra. The crystal structures were determined by X‐ray diffraction on single crystals. [Bu 2 SnL]: monoclinic, space group P2 1 /c, cell constants at 208 K: a = 860.73(5), b = 973, 51(18), c = 2340.0(3) pm, β = 93.615(11)°; R 1 = 0.0546. [Me 2 SnL]: orthorhombic, space group Pbcn, cell constants at 208 K: a = 1914.6(4), b = 1041.3(3), c = 1323.27(14) pm; R 1 = 0.0529.
