• The possibility of isolating platinum(IV) nitrate complexes to the solid phase from a nitric acid solution of platinum in the form of adducts with dibenzo-18-crown-6, 15-crown-5, and 12-crown-4 ether is studied. It is found that when nitric acid solutions containing 15-crown-5 ether (15-C-5) are evaporated, a polycrystalline product consisting of mainly a mixture of phases with the compositions (H 3 O⊂15-C-5) 2 [Pt(NO 3 ) 6 ] ( 1 ), (H 3 O⊂15-C-5) 2 (15-C-5)[Pt(NO 3 ) 6 ]·2H 2 O ( 2 ), and (15-C-5)[Pt 4 (μ 3 -OH) 2 (μ 2 -OH) 4 (NO 3 ) 10 ]·3H 2 O ( 3 ) is formed. The structure of the mentioned compounds is established by single crystal X-ray diffraction. In the case of dibenzo-18-crown-6 ether, the interaction with a nitric acid solution of platinum results in the formation of a poorly soluble tetranitro derivative of macrocyclic ether. Evaporation of nitric acid solutions of platinum containing 12-crown-4 ether does not allow the preparation of a solid crystalline phase.
