Erratum: μ-Oxalato-bis-[bis-(triphenyl-phosphine)copper(I)] dichloro-methane disolvate. Corrigendum.

An erroneous claim in the paper by Royappa et al. [Acta Cryst. (2013), E69, m126] is corrected and a reference added for a previously published report of a closely related structure.[This corrects the article DOI: 10.1107/S1600536813002080.].

In the paper by Royappa et al. (2013 ▶), the authors claimed ‘To date, no examples of copper(I) oxalate compounds containing triphenylphosphine ligands coordinated through the phosphorus atoms to the metal centers have been structurally characterized’.

However, the authors were unaware of a previous report (Jakob et al., 2010 ▶) on the structure of (PPh3)2Cu(C2O4)Cu(PPh3)2 with a different number of dichloromethane solvent molecules. The authors sincerely regret this unintentional oversight.
