The electron energy spectra of diborides of 3d-metals ScB2, TiB2, VB2, CrB2, and MnB2 are calculated ab initio. Thermodynamic properties and stability of these compounds are investigated at low temperatures. An analysis of the low-temperature heat capacity and magnetic properties of diborides has made it possible to establish a number of parameters of many-particle interactions.
