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.
