Abstract

The title compound (C6H8N)2Mo2I6(H2O)2 crystallizes in theP¯1 space group, witha = 8.127(3),b = 8.337(3),c = 10.415(4) Å, α = 73.99(2), β = 84.35(2), γ = 73.91(2) ° andZ = 1. The structure was solved by direct methods and refined to the unweighted and weighted residuals of 0.044 and 0.052. The structure is characterized by the eclipsed configuration of the iodide ions and water molecules within Mo2I6(H2O) 2−2 ion and very short Mo-Mo bond distance 2.115(1) Å. Three independent Mo-I distances are 2.784(1), 2.760(2) and 2.797(1) Å. 4-Methylpyridinium ion is planar within 0.02° Å. The compound is isostructural with (C6H8N)2Mo2Br6(H2O)2.
