  Using the toroidal compactification of string theory on n-dimensional tori,
Tn, we investigate dyonic objects in arbitrary dimensions. First, we present a
class of dyonic black solutions formed by two different D-branes using a
correspondence between toroidal cycles and objects possessing both magnetic and
electric charges, belonging to %%%% dyonic gauge symmetry. This symmetry could
be associated with electrically charged magnetic monopole solutions in stringy
model buildings of the standard model extensions. Then, we consider in some
details such black hole classes obtained from even dimensional toroidal
compactifications, and we find that they are linked to Cl(n) Clifford algebras
using the vee product. It is believed that this analysis could be extended to
dyonic objects which can be obtained from local Calabi-Yau manifold
compactifications.
