N2 - Four hexanuclear molybdenum chloride cluster complexes containing terminal thiolate ligands have been synthesized and fully characterized. (Bu 4N)2[Mo6Cl8(SEt)6] was prepared by reacting Na2[Mo6Cl8(OMe) 6] with an excess of ethanethiol in refluxing tetrahydrofuran. (PPN)2[Mo6Cl8(SBu)6], (Bu 4N)2[Mo6Cl6(SBn)6], and (Bu4N)2[Mo6Cl8(SNC8H 6)6] (C8H6NS- = 3-indolylthiolate) were subsequently prepared in the reaction of [Mo 6Cl8(SEt)6]2- with an excess of HSR (R = Bu, Bn or 3-indolyl). Single crystal X-ray diffraction analyses were performed on two of these complexes: (PPN)2[Mo6Cl 8(SEt)6]·Et2O, crystallizes in the triclinic space group P1 with a = 12.3894(11), b = 13.7651(12), c = 15.0974(13), α= 103.975(2), β = 99.690(2), γ = 98.062(2), and Z = 1; (PPh3Me)2[Mo6Cl8(SBn) 6]·2NO2CH3, also crystallizes in the P1 space group with a = 12.1574(16), b = 13.4441(17), c = 14.2132(18), α = 89.654(2), β = 88.365(2), γ = 71.179(2), and Z= 1. Our studies demonstrate that [Mo6Cl8(SEt)6]2- displays luminescent properties and that the same complex undergoes substitution reactions with different thiols, as well as reaction with electrophilic reagents such as Mel.
