which are anhydrous, compound 3 is a hemihydrate. The water molecule in 3 occupies the pores between alternating layers of the cations and anions in the crystallographic bc-plane. Compound 3 exhibits four types of weak H-bonding interactions namely N–H⋯S, N–H⋯O, O–H⋯S and C–H⋯S. All four tetrathiomolybdates decompose endothermically forming amorphous disulfides containing C and N. A comparative structural
