We report the production of ultracold heteronuclear 7Li85Rb molecules inexcited electronic states by photoassociation (PA) of ultracold 7Li and 85Rbatoms. PA is performed in a dual-species 7Li-85Rb magneto-optical trap (MOT)and the PA resonances are detected using trap loss spectroscopy. We identifyseveral strong PA resonances below the Li (2s 2S1/2) + Rb (5p 2P3/2) asymptoteand experimentally determine the long range C6 dispersion coefficients. We finda molecule formation rate (P_LiRb) of 3.5x10^7 s^-1 and a PA rate coefficient(K_PA) of 1.3x10^-10 cm^3/s, the highest among heteronuclear bi-alkalimolecules. At large PA laser intensity, we observe the saturation of the PArate coefficient (K_PA) close to the theoretical value at the unitarity limit.
