The reaction of bis(cyclopentadienyl)zircona-2,3,4,5- tetraethylcyclopentadiene (1) with antimony trichloride yields 1-chloro-2,3,4,5-tetraethyl-1-stibole (2). The reduction with potassium gives semi(tetrahydrofuran-O)bispotassium bis(2,3,4,5- tetraethylstibolide) (3). The potassium stibolide columns are linked via K-Sb contacts of 3.618 angstrom, thus forming a wavelike layer structure. The molecular structure shows three crystallographically different metal cations. One potassium atom is located between two stibolide anions, whereas the other ones show additional K-O and K-Sb contacts of 2.681 and 3.618 angstrom, respectively.
