The room temperature structure of compound 1, (C₁₀H₁₀N₂)[UO₂C_l4] (CCDC reference number 735930), has been reported with an incorrect unit cell: P−1, a = 5.5670(7), b = 8.5723(10), c = 8.8394(11) Å; α = 71.139(2), β = 73.078(2), γ = 86.534(2)°; V = 381.64(8) Å³, Z = 2. A separate spectroscopic investigation of this material (G. Liu, N. P. Deifel, C. L. Cahill, V. V. Zhurov and A. A. Pinkerton, Charge Transfer Vibronic Transitions in Uranyl Tetrachloride Compounds, J. Phys. Chem. A, 2012, 116(2), 855–864, DOI: 10.1021/jp210046j) required a low temperature (20 K) data collection and refinement to provide temperature specific structural parameters. During the course of that investigation, a room temperature (296 K) data set was also obtained and it was concluded that the original report missed a doubling superlattice at room temperature. Herein we provide new room temperature cell parameters: a = 8.9680(3), b = 9.9186(3), c = 10.4833(3) Å; α = 66.002(1), β = 87.096(1), γ = 64.555(1)°; V = 760.50(4) Å³, Z = 2, along with an updated CIF for the room temperature structure (CCDC 987400), as well as an additional refinement at 100 K (CCDC 987401) for completeness. The conclusions drawn in the manuscript are not impacted in any way. Readers may consult the spectroscopic study for the 20 K refinement (CSD 855229) which is in fact a doubled cell with respect to the correct room temperature structure.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
