Cover Feature: Crystallization of the Fundamental Tetracyanamidometallates Li4[Si(CN2)4] and Li4[Ge(CN2)4] from Polymeric Li‐T‐(NCN)‐I Precursors (T=Si, Ge) (Eur. J. Inorg. Chem. 14/2024)

The Cover Feature shows a small section of a layer in the structure of the new Li4[Si(NCN)4]. The solid‐state metathesis reaction (SSM) of mixtures of SiI4 and Li2(CN2) are controlled in situ by differential scanning calorimetry (DSC), revealing a polymeric reaction stage and the subsequent product formation under successive elimination of LiI. Tetracyanamidosilicates are closely related to orthosilicates and can exist with several cations of the PSE. As demonstrated in our previous research, metal tetracyanamidosilicates can act as robust host structures for luminescent materials to show second harmonic generation (SHG).
