Does this one suit your purposes:
([αβγδφωλμπ]-)?([([]*[A-Z☐][ub]?[a-z]?[₁₂₃₄₅₆₇₈₉₀]*()?[¹²³⁴⁵⁶⁷⁸⁹⁰]*[⁺⁻]?)?[])|,₁₂₃₄₅₆₇₈₉₀]*(·(?[-0-9.]*n?)?)?)+
This should be another kind of chemical formulae, but I will test it. What is ☐?
I dont know; I just copy from Wikidata. It is curious.
It seems to be https://en.wiktionary.org/wiki/%E2%98%90 , "ballot box" https://en.wikipedia.org/wiki/%E2%98%90
Maybe ask on the WD talk page why it is in the regex, if nobody here can help.
