Competitive Coordination of the Uranyl ion by Perchlorate and Water – The Crystal Structures of UO 2 (ClO 4 ) 2 ·3H 2 O and UO 2 (ClO 4 ) 2 ·5H 2 O and a Redetermination of UO 2 (ClO 4 ) 2 ·7H 2 O (Z. Anorg. Allg. Chem. 2003 , 629 , 1012–1016)

In the article “Competitive Coordination of the Uranyl ion by Perchlorate and Water – The Crystal Structures of UO 2 (ClO 4 ) 2 ·3H 2 O and UO 2 (ClO 4 ) 2 ·5H 2 O and a Redetermination of UO 2 (ClO 4 ) 2 ·7H 2 O” (Z. Anorg. Allg. Chem. 2003 , 629 , 1012–1016), some wrong parameters and bond lengths for UO 2 (ClO 4 ) 2 ·7H 2 O were given in table 1 and table 3 The correct parameters are: a = 1449.5(2) pm, b = 921.6(1) pm, c = 1067.5(2) pm, V = 1422.5(4)·10 6 pm 3 , ρ = 2.712 g·cm −3 , μ = 119 cm −1 . The corrected bond lengths for this structure are U–O(1) 175.8(5) pm, U–O(2) 239.1(5) pm, U–O(3) 240.8(5), U–O(4) 242.0(7). A cif file with the correct data has been deposited with the ICSD.
