1,4,7-Triazacyclononane, known as "TACN" which is pronounced "tack-en," is an aza-crown ether with the formula (C₂H₄NH)₃.^[1] TACN is derived, formally speaking, from cyclononane by replacing three equidistant CH₂ groups with NH groups. TACN is one of the oligomers derived from aziridine, C₂H₄NH. Other members of the series include piperazine, C₄H₈(NH)₂, and the cyclic tetramer 1,4,7,10-tetraazacyclododecane.
