Polymerization Isomerism in Co-M (M = Cu, Ag, Au) Carbonyl Clusters: Synthesis, Structures and Computational Investigation
Autor: Cristiana Cesari, Beatrice Berti, Francesco Calcagno, Cristina Femoni, Marco Garavelli, Maria Carmela Iapalucci, Ivan Rivalta, Stefano Zacchini
Publikováno v: Molecules, Vol 26, Iss 6, p 1529 (2021)
The reaction of [Co(CO)4]− (1) with M(I) compounds (M = Cu, Ag, Au) was reinvestigated unraveling an unprecedented case of polymerization isomerism. Thus, as previously reported, the trinuclear clusters [M{Co(CO)4}2]− (M = Cu, 2; Ag, 3; Au, 4) we

From M6 to M12, M19 and M38 molecular alloy Pt-Ni carbonyl nanoclusters: selective growth of atomically precise heterometallic nanoclusters
Autor: Cristiana Cesari, Beatrice Berti, Marco Bortoluzzi, Cristina Femoni, Tiziana Funaioli, Federico Maria Vivaldi, Maria Carmela Iapalucci, Stefano Zacchini
Molecular alloy Pt–Ni nanoclusters of increasing sizes were synthesized, their structures determined by X-ray crystallography, Pt–Ni distribution computationally investigated, and the effect of Pt–Ni replacement electrochemically studied.

Acidochromism of donor-acceptor Stenhouse adducts in organic solvent
Autor: Antonio Fiorentino, Brian Sachini, Stefano Corra, Alberto Credi, Cristina Femoni, Aurore Fraix, Serena Silvi
Publikováno v: Chemical Communications
First generation DASA derivatives can be reversibly isomerized from the coloured, open form to the colourless, closed isomer upon protonation, thus behaving as acidochromic compounds in halogenated organic solvent.

2-D Molecular Alloy Ru-M (M = Cu, Ag, and Au) Carbonyl Clusters: Synthesis, Molecular Structure, Catalysis, and Computational Studies
Autor: Cristiana Cesari, Marco Bortoluzzi, Francesca Forti, Lisa Gubbels, Cristina Femoni, Maria Carmela Iapalucci, Stefano Zacchini
The reactions of [HRu3(CO)11]- (1) with M(I) (M = Cu, Ag, and Au) compounds such as [Cu(CH3CN)4][BF4], AgNO3, and Au(Et2S)Cl afford the 2-D molecular alloy clusters [CuRu6(CO)22]- (2), [AgRu6(CO)22]- (3), and [AuRu5(CO)19]- (4), respectively. The rea

Synthesis, molecular structure and fluxional behavior of the elusive [HRu4(CO)12]3− carbonyl anion
Autor: Cristiana Cesari, Marco Bortoluzzi, Cristina Femoni, Maria Carmela Iapalucci, Stefano Zacchini
The elusive mono-hydride tri-anion [HRu4(CO)12]3- (4) has been isolated and fully characterized for the first time. Cluster 4 can be obtained by the deprotonation of [H3Ru4(CO)12]- (2) with NaOH in DMSO. A more convenient synthesis is represented by
