6. In view of the weak coordination of the donor atom at the 8-position of the 1-naphthyl group, it may be better to describe the resulting structures as [4+1]-coordinate. However, we prefer to call them "pentacoordinate" for the sake of simplicity.

15. The S1⋯Si1 distance in 1a and the Se1⋯Si1 distance in 1c correspond to ca. 78% and ca. 79% of the sum of the van der Waals radii, respectively. These ratios lie between those of O1⋯Si1 in 1i (ca. 75%) and N1⋯Si1 in 1e (ca. 81%).
