<jats:title>Abstract</jats:title><jats:p> The reactions of cyclopentadienyl dicarbonyl tetrahydrofuran manganese, CpMn(CO)<jats:sub>2</jats:sub>(OC<jats:sub>4</jats:sub>H<jats:sub>8</jats:sub>), with either COS or COSe lead preferentially to binuclear complexes, Cp<jats:sub>2</jats:sub>Mn<jats:sub>2</jats:sub>(CO)<jats:sub>4</jats:sub>S<jats:sub>2</jats:sub> and Cp<jats:sub>2</jats:sub>Mn<jats:sub>2</jats:sub>(CO)<jats:sub>4</jats:sub>Se<jats:sub>2</jats:sub>, respectively. According to an X-ray crystallographic study, the sulfur complex is a centrosymmetric molecule containing a planar Mn-(S-S*)-Mn* unit with d(Mn-S) 216.7(4) pm, d(S-S*) 200.7(6) pm and &lt; MnSS* 114.4(2)°.</jats:p>

Formation of Pt-S-Mn groups in platinum triphenylphosphine complexes with cymanthrenylthiolate ligands

“…Commercial CpMn(CO) 3 and H 2 PtCl 6 •6H 2 O were used without additional purification. Dicymanthrenyl di sulfide was synthesized according to a known procedure.…”

“…It was of interest to synthesize a platinum cis tri phenylphosphine complex containing the cymanthrenyl thiolate ligands (cymanthrenyl is C 5 H 4 Mn(CO) 3 ), use this complex for generating radicals by replacing the carbonyl group at the manganese atom with SR groups, and study delocalization of lone electrons throughout the molecule by ESR spectroscopy. However, it was unexpectedly found that only intramolecular replacements of CO by the sulfur atoms of the cymanthrenylthiolate ligands occur giving rise to new sulfide bridged heterometallic groups.…”

Reaction of transition metal carbonyls with soluble polyselenides: synthesis and structure of [(C6H5)4P]2[Re2(Se4)2(CO)6]

“…There have been relatively few binary manganese and rhenium sulfides and polysulfides reported (2, 3). Several complexes containing selenide atoms coordinated to manganese (4) and rhenium (5) centers have also been described, and one has been characterized (5a). However, to our knowledge, there have been no soluble polyselenides or binary selenide anions of group 7 metals reported or characterized.…”

[Fe2(Sb2S6)(CO)6]2+: A Cationic Group 15/16 Metal Cluster

“…The S-S bonds in coordinated metal disulfides normally range from 1.96 to 2.05 Å. 18, [24][25][26][27] The [SbF 6 ] -counterions and SO 2 molecules of solvation are normal in all respects and will not be mentioned further.…”
