Scatter plot of Y−Zn···O (Y = N or O) angle versus the Zn···O distance that are in acceptable range of spodium bond extracted from the CSD data. The vertical dashed lines mark the data involved in sum of the van der Waals radius overlap according to Bondi’s and Hu and Robertson van der Waals radius for zinc and oxygen atoms.
