Abstract

Treatment of [{Mo(µ-Br)Br(CO)4}2] with 3,3,7,7,11,11,15,15-octamethyl-1,5,9,13-tetrathiacyclohexadecane (Me8[16]aneS4) in CH2Cl2 gave the crystallographically characterised, seven-co-ordinate, ionic complex [MoBr(CO)2(Me8[16]aneS4)][MoBr3 (CO)4] 1. Reaction of 2 equivalents of [MI2(CO)3(NCMe)2] (M = Mo or W) with 1 equivalent of Me8[16]aneS4 afforded the analogous iodo-complex [MoI(CO)2(Me8[16]aneS4)][MoI3 (CO)4] 2 and the crystallographically characterised complexes [WI(CO)2(Me8[16]aneS4)][WI3 (CO)4] 3 and [WI(CO)3(Me8[16]aneS4)][WI3 (CO)4] 4. The cations in complexes 1 and 3 have distorted capped-trigonal-prismatic geometries whereas that in 4 has a geometry lying between capped octahedral and capped trigonal prismatic. The anions of all three complexes have capped-octahedral geometries. Treatment of 2 equivalents of [MI2(CO)3(NCMe)2] with 1 equivalent of 1,5,9,13-tetrathiacyclohexadecane ([16]aneS4), 1,4,8,11-tetrathiacyclotetradecane ([14]aneS4) or 1,4,7,10-tetrathiacyclododecane ([12]aneS4) yielded the bimetallic thioether-bridged complexes [M2I4(CO)6([n]aneS4 -S,S′,S″,S ‴)] (n = 16, M = Mo; n = 14, M = Mo or W; n = 12, M = Mo), and the ionic complexes [WI(CO)2([n]aneS4)][WI3(CO) 4] (n = 16 or 12). The relationships between the various products of these reactions are discussed. Reaction of [16]aneS4 with [MoCl3(thf)3] (thf = tetrahydrofuran) gave a polymeric complex of empirical formula [Mo3Cl9([16]aneS4)2] plus the dinuclear, ionic complex [Mo2Cl5([16]aneS4-S,S ′)2]Cl.
