DOI: 10.1002/qua.25436
Abstract: Proposing new valence electron counting rules and new structural motifs are both very important in chemistry. In this work, we unexpectedly found that by introducing a π-type skeleton YCCY (Y = Al/Ga/In/Tl), a total of sixteen novel… read more here.

DOI: 10.1080/00268976.2017.1417645
Abstract: ABSTRACT Contrasting the big family of the planar tetracoordinate carbon (ptC), species featuring the planar tetracoordinate heavier group element M (ptM) have been largely limited. Effective structural frameworks to accommodate such ptM centres are thus… read more here.
