In all probability, it has not been experimentally determined due to the extraordinarily small quantities in existence. However, by extrapolating data from other hydrogen halides, namely HCl HBr and HI, which boil respectively at -85, -66 and -34 degrees C, one could reasonably expect that HAt would boil around -5 degrees C (+/- 5 degrees).
