Abstract

The aromaticity in 2,3-pyrido-annulated 1,3,2λ2-diazatetroles C5H3N(NR)2EII (EII = C, Si, Ge, Sn, Pb) was studied using a set of experimental and calculated criteria: UV-VIS, Raman, ISE, NICS, GIMIC and EDDB. The data obtained indicate either a slight decrease in aromaticity (NICS, GIMIC, ISE methods) or equal aromaticity (UV-VIS, ISE methods) compared to benzo-annulated analogues C6H4(NR)2E. The π-aromaticity increases down the group from Si to Pb.
