176264	2016-02-08	cif/ (antanas@kurmis) Updating the space group and cell constants for entries 9014589, 9015586 after consulting the original paper. It seems that a standard cell setting was used instead of the non-standard one reported in the paper. Due to changes in these parameters the crystal density and chemical formula sum was also updated. Both entries were also marked as duplicates of entry 1010931.	9015586.cif
