The spectra of the (N$2$O)$2$-C$2$H$2$ and ((N$2$O)$2$-C$2$D$2$ trimers in the region of the N$2$O $\nu 1$ fundamental (~2224 cm-1) are observed using a tuneable diode laser to probe a pulsed supersonic slit jet expansion. The observed bands have c- and b-type rotational structure and the trimer has C$2$ symmetry. The structure of the trimer can be thought of as a nonpolar N$2$O dimer with a C$2$H$2$ monomer lying above the dimer plane. Search for the other possible isomers of the trimer is currently underway.
