 The molecule was detected in the six lower energy //a//-type transitions between 8 and 45 GHz. It was not seen in two higher energy transitions. This and the appearance largely in absorption suggests the molecule to be present in the colder and less dense envelope of Sgr B2(N). The molecule can be viewed as a derivative of the ubiquitous, small aromatic cyclopropenylidene, //c//-C<sub>3</sub>H<sub>2</sub>. The molecule was detected in the six lower energy //a//-type transitions between 8 and 45 GHz.

 The molecule was detected in the 7<sub>1,6</sub> – 6<sub>1,5</sub> transition near 103.1 GHz toward four of seven dark clouds employing the IRAM 30 m telescope. The four sources are TMC-1, B1-b, L483, and Lupus-1A. The molecule was detected in the 7<sub>1,6</sub> – 6<sub>1,5</sub> transition near 103.1 GHz toward four of seven dark clouds employing the IRAM 30 m telescope.
