There are infinitely many solutions -- just what sort of representation are you looking for? One such is the equation

Exp[z] == -I

which can be plugged in to Reduce:

In[1]:= Reduce[ Exp[z] == -I, {z}]

Out[1]= C[1] \[Element] Integers && z == -((I \[Pi])/2) + 2 I \[Pi] C[1]

Or get all (finite many) solutions in a certain domain:

In[2]:= Reduce[2 \[Pi] < Im[z] < 6 \[Pi] && Exp[z] == -I, {z}]

Out[2]= z == (7 I \[Pi])/2 || z == (11 I \[Pi])/2
