The magnetic and magnetodielectric properties of bismuth pyrostannate 
(
and 0.2) have been examined. Using the Mössbauer spectroscopy and electron paramagnetic resonance, the high-spin state and crystallographic positions of iron ions have been established. The coexistence of triclinic symmetry domains in the 
compound with the monoclinic symmetry below 140 K has been found. For the 
composition with 
, the nonlinear field dependence of magnetization in the paramagnetic region up to room temperatures has been observed. The electric polarization hysteresis and the magnetoelectric effect in the compound have been disclosed. The magnetic field-dependent anomalous behavior of magnetization has been explained by the magnetoelectric effect.
