In 2013, Cabezas et al. reported the detection of
hydromagnesium isocyanide (HMgNC) both in the laboratory and toward IRC+10216. The observations were made with the
IRAM 30m telescope on
Pico Veleta in Spain. The detection has not yet
been confirmed or supplemented with observations toward other sources or with isotopic substitutions. HMgNC was
formed in the lab by ablating a Mg rod with a laser in very dilute ethylcyanide.
HMgNC is a linear molecule related to the first Mg-containing species that was discovered, magnesium isocyanide,
