The crystal structure of Di-nitratobis (ethylcaprolactam)uranyl (Ⅱ) UO₂ [CH₂ (CH₂)₄ CONC₂H₅]₂ (NO₃)₂ was established by a single-crystal X-ray diffraction study.It is triclinie, space group P1, with a=7.171 (2), b=8.655 (3), c=10.182 (5)Å, α=78.27 (3), β=70.63 (3), γ=81.76 (3)°, V=581.7 (4)Å³, Z=l, Dc=1.94 g.cm^-3.Final R value is 0.0218.The result reveals that uranyl ion is coordinated to six oxygen atoms, two of them are from two carbonyl groups of ethylcaprolactam and the other four are from two nitrate groups.
