This review surveys the synthesis and reactivity of low-oxidation state metalate anions of the
d-block elements, with an emphasis on contributions reported between 2006 and 2022 …

The first consistent series of mononuclear 17‐electron complexes of three Group 7 elements
has been isolated in crystalline form and studied by X‐ray diffraction and spectroscopic …

Reactions of the alkyl isocyanide fac-[Tc (CO) 3 (CNR) 2Cl] complexes (2)(CNR= CN n Bu or
CN t Bu) with the sterically encumbered isocyanide CN p-FArDarF2 [DArF= 3, 5-(CF3) …

A metal-to-ligand charge transfer with mixed intraligand character is observed for the
rhenium hexakisarylisocyanide complex [Re (CNAr) 6] PF6 (CNAr= 2, 6 …

Organometallic approaches are of ongoing interest for the development of novel functional
99mTc radiopharmaceuticals, while the basic organotechnetium chemistry seems frequently …

A series of technetium complexes with the sterically encumbered m-terphenyl isocyanides
CNArDipp2 (Dipp= 2, 6-diisopropylphenyl) and CNArMes2 (Mes= 2, 4, 6-trimethylphenyl) …

The first technetium complexes containing anionic alkynido ligands in an end-on
coordination mode have been prepared by using the nonprotic, cationic precursor mer, trans …

The fac–mer rearrangements in [MX3 (CO) 3] 2−(M= Re, 99Tc) induced by a pincer-type
ligand (PNP) and a “halide scavenger” are reported. The reactions of fac-[99mTc (CO) 3 …

[Re (CO) Br (CNArDArF2) 4] and [Tc (CO) Cl (CNArDArF2) 4](ArDArF= 2, 6-(3, 5-(CF3)
2C6H3) 2-4-F-C6H2) were prepared by reactions of [Re (CO) 5Br] or (NBu4)[Tc2 (CO) 6 (μ …

Nitriles and isonitriles are important σ-donor ligands in coordination chemistry. Isonitriles
also function in low-valent complexes as π-acceptor ligands similar to CO. Herein we …
