Stabilization of thallium(I) Pd 9 TlPd 3 sandwich monocation with octahedral-based [Pd 9 (CO) 9 (PMe 3 ) 6 ] and [Pd 3 (CO) 3 (PMe 3 ) 3 ] entities versus unstable Pd 3 Tl(I)Pd 3 sandwich monocation with [Pd 3 (CO) 3 (PEt 3 ) 3 ] entities: Comparative computational implications

Publikováno v: Journal of Cluster Science. 25:205-224

This article presents the personal saga of one of the authors (LFD) in the determination of the solid-state structure of Fe3(CO)12. We also present the results of our recent determination of its solid-state structure at low temperature (100 K), in wh
