Mechanochemical Reactions of Molybdenum and Tungsten Chalcohalides with (Bu4N)2[Zn(Dmit)2]. Crystal Structure of (Bu4N)2[Mo3Se_(5.88)S_(1.12)(Dmit)3] · 1.15CH2Cl2

摘要

The mechanochemical reactions of cluster chalcohalides M3Q7X4 (M = Mo, W; Q = S, Se, Te; X = Br, I) with (Bu4N)2[Zn(Dmit)2] (Dmit is 1,3-dithia-2-thionedithiolate, C3S_5~(2-)) are studied. It is shown that the reaction of Mo3Se7Br4 with (Bu4N)2[Zn(Dmit)2] followed by crystallization from CH2Cl2 results in the formation of a new compound of the composition (Bu4N)2[Mo3Se_(5.88)S_(1.12)(Dmit)3] · 1.15CH2Cl2 (I) characterized by IR spectroscopy, electrospray mass spectrometry, and X-ray structure analysis. Under similar conditions, W3Q7Br4 and Mo3Te7I4 form binuclear complexes [M2O2Q2(Dmit)2]~(2-) identified by electro-spray mass spectrometry. Various types of nonvalent contacts Q—Q are observed in the crystal structure of compound I.
