Notable achievement of our chemists [The first work of Ukrainian chemists, published in the journal Nature]
A new world record for the length of the carbon bond C-C currently is 1.704 Ao (typically 1,540 Ao). Remarkable is that despite on the record bounding length, synthesized compounds are stable even at elevated temperatures. The result was so unpredictable that it was necessary to undertake specific study causes of anomalous stability and this has led to fundamental discovery.
