Reactions of (NBu4)[ReOCl4] with N-(N??, N??-dialkylaminothiocarbonyl)-N?-(2-
hydroxyphenyl)benzamidines (H2L1) give complexes of the compositions [ReOCl(L 1)] (1), cis-[ReO(L1
)(OMe)] (2), or cis,cis-[{ReO(L 1)}2O] (3) depending on the conditions applied. Compound 3 contains a
bridging oxygen atom in the cis position to the terminal oxido ligands of both rhenium atoms. The analogous
dimeric, sulfur-bridged compound [{ReO(L1)}2S] (4) was obtained by the reaction of 1 with Na2S.
Complexes with the unusual oxidorhenium(V) cores, cis-{ReO(OR)}3+, cis,cis-{ORe-O-ReO}4+, and
cis,cis-{ORe-S-ReO}4+, are formed from the reaction of [ReOCl 4]- and N-(N??,N??-
dialkylaminothiocarbonyl)- N?-(2-hydroxyphenyl)benzamidine ligands depending on the conditions applied.
