A change in the formula of innelite

In the IMA List of Minerals the chemical formula of innelite appears as
Ba4Ti2Na(NaCa)Ti(Si2O7)2[(SO4)(PO4)]O2[O(OH)]. It is marked as “2016 s.p.”, after the approval in 2016 of the proposal on the seidozerite supergroup. In that proposal, as well as in the published paper [Mineralogical Magazine, 81, 1457–1484 (2017)] innelite has Mn2+ instead of Ca. It has been ascertained that the wrong formula in the IMA list arises from a mere typing mistake. Accordingly the formula of innelite is modified to Ba4Ti2Na(NaMn2+)Ti(Si2O7)2[(SO4)(PO4)]O2[O(OH)]. Thanks to Fernando Cámara for spotting it.

Stannopalladinite: revised formula

Recently, a paper was published [Mineralogical Magazine, 87, 773–782 (2023)] dealing with the re-evaluation of the grandfathered mineral stannopalladinite, described in 1947 [Doklady Akademii Nauk SSSR, 58, 1137–1140 (1947)], whose formula is currently given in the IMA List of Minerals as Pd3Sn2 (?). Based on new electron microprobe data the empirical formula of the mineral turned out to be (Pd2.42Cu0.56Pt0.02)Σ3.00(Sn0.92Pb0.08)Σ1.00. Most likely the new analytical data were obtained on holotype stannopalladinite, although the studied sample, taken from the collections of the Fersman Mineralogical Museum, was not officially catalogued as such. The poor quality of the available material prevented a SCXRD study to be carried out, and in the lack of structural information it is still uncertain whether Cu is a species-forming element, or if it a subordinate element partially substituting for Pd. For that reason the authors of the re-evaluation of stannopalladinite could not apply for an official re-definition of the mineral. However, since the new data seems reliable, and the proposed new formula has a different palladium/tin ratio, it was agreed to modify the chemical formula of stannopalladinite in the IMA List of Minerals (which is by definition a work in progress) from Pd3Sn2 (?) to (Pd,Cu)3Sn. This is an executive decision taken
