We had obtained from the histitute of Organic Chemistry of the University of Zurich (Prof. H.-J. Hansen), where the Werner collection is located, a sample of die cobalt complex prepared by Werner s British co-worker. The measurement of the CD-spectrum of a solution obtained from one crystal of the original sample shows clearly its optical activity (Figure 1). After 90 years on the shelves of the University of Zurich, the compound had not changed in any way.
