The λ6Si-silicate [K(18-crown-6)]2[Si(NCO)6] (10) was synthesized by treatment of Si(NCO)4 with KNCO in the presence of 18-crown-6. Compound 10 (SiN6 skeleton) is the first example of a hexa(cyanato-N)silicate. It was characterized by solid-state and solution NMR spectroscopy, and the acetonitrile solvate 10·2CH3CN was studied by single-crystal X-ray diffraction. To differentiate between the two isomeric [Si(NCO)6]2− and [Si(OCN)6]2− dianions, computational studies were performed.
