[Cu30I16(mtpmt)12(μ(10-S4))]: an unusual 30-membered copper(I) cluster derived from the C-S bond cleavage and its use in heterogeneous catalysis.

The Cu(I)-mediated C-S bond cleavage of 5-methyl-4-(p-tolyl)pyrimidine-2-thiol (mtpmtH) gave one 30-nuclear cluster [Cu30I16(mtpmt)12(μ10-S4)], one polymeric complex [(bmtpms)Cu-(μ-I)]n and one tetranuclear complex [(bmptmds){Cu(μ-I)}2]2; the 30-nuclear cluster displayed excellent catalytic performances in the coupling reactions of N-heterocycles and arylboronic acids and could be recycled and reused.
