Abstract
The reaction of Ni(OAc)2 with Li[S-2,4,5-Pri 3C6H2] and [Ph4P]Br in a 1 : 5 : 1 ratio produces [PPh4][Ni2(S-2,4,5-Pri 3-C6H2)5]1; the anion of 1 was shown by X-ray crystallography to possess the rare face-sharing bitetrahedral geometry—the face-sharing [Ni(µ2-SR)3Ni] unit is described by acute Ni–S–Ni angles of 69° and a short Ni–Ni interaction of 2.607 Å.Keywords
