Unsystematische Zinkchemie: zufällige Bildung und Struktur von Zn6(SC6F5)10(BPPAE)2
Authors:Bodo Müller  Heinrich Vahrenkamp
Abstract:Non‐systematic Zinc Chemistry: Accidental Formation and Structure of Zn6(SC6F5)10(BPPAE)2 The reaction between pyridine‐2‐carbaldehyde and ammonia‐contaminated zinc‐bis(pentafluorothiophenolate) yielded, beside the expected 1 : 1 adduct, small amounts of the hexanuclear cluster Zn6(SC6F5)10(BPPAE)2. Its ligand BPPAE (1,2‐bis‐pyridine‐2‐yl‐2(pyridine‐2‐ylmethylene)‐amino]‐ethenolate) results from condensation of three molecules of pyridine‐2‐carbaldehyde with one molecule of ammonia. The Zn6 cluster consists of two centrosymmetrically arranged Zn3 units which contain three differently coordinated zinc ions in ZnS4, ZnS2ON and ZnSON3 environments.
Keywords:Zinc  Cluster compounds
