A New “Dimer-of-Dimers” Complex Derived from Axial Coordination of 7,7,8,8-Tetracyanoquinodimethane to Ru(II,III) Cation Dimer
The “dimer-of-dimers” complex of ruthenium(II,III) pivalate cation dimer [{Ru2(O2CCMe3)4}2(μ-tcnq)(H2O)2](BF4)2 (1) (tcnq=7,7,8,8-tetracyanoquinodimethane) has been prepared and characterized. The X-ray structure analysis of 1 showed that tcnq connects the Ru(II,III) dimers with an Ru-N distance of...

| Zusammenfassung: | The “dimer-of-dimers” complex of ruthenium(II,III) pivalate cation dimer [{Ru2(O2CCMe3)4}2(μ-tcnq)(H2O)2](BF4)2 (1) (tcnq=7,7,8,8-tetracyanoquinodimethane) has been prepared and characterized. The X-ray structure analysis of 1 showed that tcnq connects the Ru(II,III) dimers with an Ru-N distance of 2.323(7) Å. The Ru-Ru distance 2.263(1) Å is nearly the same as that of the parent cation dimer [Ru2(O2CCMe3)4]+ (2.260(1) Å). The antiferromagnetic interaction between the Ru(II,III) cores through the tcnq molecule is fairly weak. |
