multinuclear (1H, 13C) NMR spectroscopy and mass spectrometry. The crystal and molecular structures of 1–5 and 11 were determined by single-crystal X-ray diffraction. In all compounds the (C6H4CH2)N nitrogen atoms are coordinated to bismuth. The crystals of 1 and 2, as well as those of the chlorides 3 and 4, contain discrete molecules.
