The 40 m Centro Astronómico de Yebes dish and the IRAM 30 m dish were employed to observed 22 rotational transitions of magnesium monodiacetylide, MgC<sub>4</sub>H, between 33 and 111 GHz toward the famous near-by carbon-rich AGB star CW Leonis. The authors label 8 transitions between 71 and 108 GHz as observed with two fine structure components and one with one. The astronomical data were employed to derive spectroscopic parameters in the absence of laboratory data.\\ | The 40 m Centro Astronómico de Yebes dish and the IRAM 30 m dish were employed to observe 22 rotational transitions of magnesium monodiacetylide, MgC<sub>4</sub>H, between 33 and 111 GHz toward the famous near-by carbon-rich AGB star CW Leonis.

| The 40 m Centro Astronómico de Yebes dish was employed to observe 22 rotational transitions of magnesium monotriacetylide, MgC<sub>6</sub>H, between 31.0 and 50.3 GHz toward the famous near-by carbon-rich AGB star CW Leonis. |
