OptRI sets matched to the cc-pVnZ-PP-F12 orbital sets for the heavy p-block elements are available, and the present aim is to adapt these auxiliary sets for the aug-cc-pVnZ-PP-F12 orbital sets also developed in this work. Matching previous development of OptRI sets, the 3C ansatz was used along with a geminal Slater exponent of 1.4 a -1 0 . The (m -1)d electrons were included in the frozen-core approximation, and a steep penalty function was applied such that the ratio between any new exponent and an existing exponent, in either the orbital or auxiliary basis, is greater than or equal to 1.3. All calculations involving δ RI were carried out in a locally modified version of the Molpro package, with optimizations using the Nelder-Mead simplex algorithm. The reference ABS used was the large, even-tempered set used in the orbital basis set development.
