Monosubstituted amidinate complexes [RC(NR)2]ECl2 [E = Sb, R = tBu, R = iPr 1, Cy 2, 2,6-iPr2C6H3 (Dipp) 3; R = nBu, R = iPr 4; E = Bi, R = tBu, R = iPr 5, Dipp 6] were prepared in high yields by salt elimination reactions of ECl3 with Li amidinates. 1-6 were characterized by elemental analyses, NMR and IR spectroscopy and single-crystal X-ray diffraction. In addition, computational calculations were performed to clarify the different bonding modes in 1 and 5.
