We carried out specific numerical studies for pairs of ultracold KRb and RbCs molecules, leading to the production of (KRb)2 and (RbCs)2 complexes. The results and conclusions were generalized to larger complexes based on universal properties of long-range interactions between polar molecules. Thus, we identified several triatomic and tetratomic linear polar molecules with favorable ratios of dipole and quadrupole electric moments for which the proposed approach could be used. Such cold or ultracold complexes should also be stable enough to allow experimental confirmation.
