  "abstract": "Reactions of [Ph₃C]⁺[Al{OC(CF₃)₃}₄]⁻ with [Ae{N(SiMe₃)₂}₂]₂ (Ae = Ca, Sr) or [Ba{N(SiMe₃)₂}₂(THF)]₂ have been studied in benzene, mesitylene and chlorobenzene. Irrespective of Ae identity, interrogation of the bulk constitutions of the resultant systems was complicated by liquid clathrate formation. X-ray diffraction analysis of single crystals, however, identified the formation of bimetallic dications, [(η⁶-C₆H₆)Ae-μ-N(SiMe₃)₂]₂²⁺, and monometallic monocations, [(η⁶-1,3,5-Me₃C₆H₃)₂Ae-κ¹-N(SiMe₃)₂]⁺ from benzene and mesitylene, respectively. In contrast, only the strontium system provided any indication of similar binding of chlorobenzene. Although these observations infer a greater binding affinity for the more electron rich arene derivative, in no case could any significant perturbation of the arene structure be identified. DFT calculations on the isolated cationic structures are consistent with this viewpoint, confirming the energetic similarity of both structural types and describing a decreasing affinity for arene binding in the order Ca > Sr > Ba. These calculations also invoke a notable level of nd-orbital participation in arene binding by [(Me₃Si)₂NAe(η⁶-arene)]⁺, which is all but negated by the adoption of an alternative silazide-bridged structure.",
