A size distribution of neutral SnN clusters with 6 <= N <= 600 is deposited on a bimetallic micromechanical sensor and the released heat during the cluster deposition can be determined from the time-dependent bending of the sensor. The size distribution of the deposited clusters coming from the pulsed source has been probed with a quasicontinuous time-of-flight mass spectrometer. The formation enthalpy per atom of the investigated SnN cluster size distribution is obtained from the measured calorimetric heat to Delta hf,298 = 0.45�0.53 eV.
