Sodium and Potassium tert-Butyl Peroxide Hydrates: Crystal Structure and Properties

Abstract Sodium and potassium tert- butyl peroxide hydrates 2Na + ·2C 4 H 9 $${\text{O}}_{2}^{ - }$$ ·7H 2 O ( I ) 2K · 2C ·4H II were prepared. According to X-ray diffraction data (CIF files CCDC no. 2081025 2081024 )), the compounds are coordination polymers in which alkali metal atoms have C.N.(Na) of 6 or C.N.(K) 8. The crystal packings comprise layers with clearly defined hydrophobic surfaces consisting hydrocarbon groups hydrophilic inner areas including water molecules, cations, peroxy tert -butyl anions. Compounds characterized by vibrational spectroscopy, 1 H, 13 C NMR thermogravimetry, differential scanning calorimetry.
