Facile Route to Rare Heterobimetallic Aluminum–Copper and Aluminum–Zinc Selenide Clusters

Heterobimetallic aluminum–copper and aluminum–zinc clusters were prepared from the reaction of LAl­(SeH)2 [1; L = HC­(CMeNAr)2 and Ar = 2,6-iPr2C6H3] with (MesCu)4 and ZnEt2, respectively. The resulting clusters with the core structures of Al2Se4Cu4 and Al2Se4Zn3 exhibit unique metal–organic frameworks. This is a novel pathway for the synthesis of aluminum–copper and aluminum–zinc selenides. The products have been characterized by spectroscopic methods and single-crystal X-ray structural characterization.
