(18-Crown-6-κ⁶O){(tri­methyl­sil­yl)[6-(tri­methyl­silyl­amino)­pyridin-2-yl-κN¹]aza­nido-κN}potassium(I)

The title complex, [K(C₁₁H₂₂N₃Si₂)(C₁₂H₂₄O₆)], contains a single K⁺ cation coordinated by a monoanionic (6-tri­methyl­silyl­amino­pyridin-2-yl)(tri­methyl­sil­yl)aza­nide (HL) ligand and an 18-crown-6 ligand. One SiMe₃ group in HL is disordered over two positions, with an occupancy ratio of 0.727 (7):0.273 (7). The K⁺ cation is eight-coordinated, distributed between the pyridyl and aza­nide N atoms of HL, forming a four-membered ring, and a κ⁶ 18-crown-6 ligand. The complex is best described as a contact ion pair and, unlike other similar literature examples, this complex does not dimerize. No inter­molecular hydrogen bonding is observed in the crystal structure, likely indicating that weak electrostatic inter­actions are the dominant feature directing the crystal packing.
