Herein we present the oxidation of base-stabilized tetrel(II) dications [LM][OTf](2) [L = BIMEt3 = tris(1-ethyl-benzoimidazol-2-ylmethyl)-amine and M = Ge, Sn] with PCl5, SeCl4, Br-2, and I-2 to access dicationic dihalides [LMX2] [OTf](2). The addition of oxygen-rich donor molecules (picoline N-oxide, OPEt3) to dications [LM][OTf](2) yielded donor-acceptor complexes bearing a tetrel(II) dication adjacent to a pnictogen(V) moiety. The addition of elemental sulfur to [LGe][OTf](2) yielded [(LGeS)(2)][OTf](4) containing a dimeric tetracation.
