Description
Xingyu Yang's team caught a lasting germylyne radical, a heavy twin of a carbyne, that joins into a pair and back through a Ge-Ge bond. Reversible radical pairing underpins bond making and breaking. Capturing it in a stable heavy carbyne had remained out of reach.
The radical proved stable in air, dimerised cleanly with a visible heat-colour change, and was mapped by variable-heat scans and crystal scans, revealing a middling bond strength. Beyond pairing it cut sulfur-sulfur, Se-Se, P-P, and even stubborn ring carbon-chlorine bonds, giving a platform for quick materials and radical firing chemistry.
