    Title: Chalcogenido-Bridged Clusters by Reactions of Chalcogenostannate Salts
    Author: Zimmermann, Christian; Anson, Christopher; Dehnen, Stefanie
    Subject: Chalcogenido-bridged clusters ; chalcogenostannates ; X-ray diffractometry
    Description: Reactions of [ en H] 4 [Sn 2 S 6 ] or K 6 [Sn 2 Te 6 ] with [Cp*CoCl] 2 (Cp* = C 5 Me 5 ), or [ en H] 4 [Sn 2 Se 6 ]· en ( en  = 1,2-diaminoethane) with [{CpFe(CO) 2 } 2 SnCl 2 ] leads to the formation of three chalcogenido-bridged transition metal complexes via an unusual synthesis route. [(Cp*Co) 3 ( μ 3 -S) 2 ] ( 1 ), [(Cp*Co) 3 ( μ 3 -Te) 2 ] ( 2 ), and [{CpFe(CO) 2 } 3 {CpFe(CO)}Sn 3 Se 4 ] ( 3 ) were structurally characterized by means of single-crystal X-ray diffractometry and represent previously unknown homologues of a selenium bridged analogue ( 1 or 2 ) or of Fe–S clusters ( 1 or 3 ). Compounds 1 and 2 , together with the previously reported Se analogue, show a progression from a symmetrical closo -trigonal-bipyramidal structure to the square-pyramidal structure predicted by the Wade-Mingos Rules for a 50 electron cluster.
