名称:
Charge-transfer salt of bis(cis-1,2-diphenylethene-1,2-dithiolato)palladate(1 –) with cobaltocenium, and neutral bis(cis-1,2-diphenylethene-1,2-dithiolato)palladium
摘要:
The crystal structure of the charge-transfer salt cobalto-cenium bis(cis-1,2-diphenylethene-1,2-dithiolatato)palladate(1-), [CO(C5H5)(2)][Pd{S2C2(C6H5)(2)}(2)], consists of linear -D(+)A(-)D(+)A(-)D(+)A(-)- chains. The [Co(C5H5)(2)](+) cation adopts an approximately eclipsed D-5h configuration. The stereochemistry of the [Pd{S2C2(C6H5)(2)}(2)](-) anion is largely similar to that of the neutral molecule, bis(cis-1,2-diphenylethene-1,2-dithiolato)palladium, [Pd-{S2C2(C6H5)(2)}(2)], the structure of which has also been determined; however, the Pd atom of the former has a distorted square-planar environment, while the PdS4 chromophore of the latter is strictly planar. Furthermore, the former has longer Pd-S and S-C distances, and shorter C-C distances (in the chelate rings) than the latter.
