The "selective" protonolysis of the β-diketiminato calcium derivative [Ca{(NDippCMe)2CH}{N(Si-Me3)2}(THF)] (Dipp = C6H3iPr2-2,6) with a selection of terminal alkynes has produced a series of dimeric acetylides [Ca{(NDippCMe)2CH}{μ-CsCR}]2, which have been characterized in solution and in the solid state. The asymmetry of the Ca-C-Ca' bridges is subtly dependent upon the extent of "side-on" (π-type) interaction between the acetylide unit and the Ca' centers.
