13. 4, and after dry nitrogen was passed through the products on the filter tube, the strong odor of pyridine was removed. Most products treated in this way analysed well for one pyridine molecule per trimer complex (N = 4.25 ± 0.045%. seven determinations), and they lost only a little pyridine when heated in air at ca. 120° for several hours (4.29 down to 4.22%; 4.33 down to 4.23%). But a few were significantly low, e.g. one well-crystallized sample, N = 3.83%, and it seems possible that pyridine content varied from one crystal to another.

15. The original structure determination at room temperature was of low accuracy and did not detect the uncoordinated pyridine. In the presence work a different crystal was used, from the same batch.
