Tetrapyridinium μ-oxido-di-μ-sulfato-bis[chloridodioxidomolybdate(VI)]

Tetrapyridinium μ-oxido-di-μ-sulfato-bis[chloridodioxidomolybdate(VI)]

The title salt, (C5H6N)4[Mo2Cl2O5(SO4)2], comprises four pyridinium cations for each [(MoClO2)2(μ-O)(μ-SO4)2]4− anionic unit. The asymmetric unit consists of three aggregates of the empirical formula. The tetraanionic bimetallic molybdenum(VI) cluster is unpre...
