Hypercoordinated diorganopnicogen(III) compounds based on a butterfly-like skeleton of type [CH3OCH2CH2N(CH2C6H4)2]M (M = Sb, Bi)

New diorganopnicogen(III) compounds of type [CH3OCH2CH2N(CH2C6H4)2]ML (M = Sb, L = ONO2 (3), OSO2CF3 (4); M = Bi, L = ONO2 (5), OSO2CF3 (6), OSO2C6H4(CHCH2)-4 (7) based on a heterocyclic butterfly-like tetrahydro-dibenzo[c,f][1,5]azastibocine/azabismocine skeleton were prepared by ligand exchange reactions between [CH3OCH2CH2N(CH2C6H4)2]MX (M = Sb, X = Cl (1); M = Bi, X = Br (2) and the appropriate silver salt. The new compounds 1 and 3–7 were...
