TL;DR: A new geometric parameter for four-coordinate compounds, tau(4), is proposed as an improved, simple metric for quantitatively evaluating the geometry of four- coordinate complexes and compounds.

TL;DR: Two mixed-valence copper complexes were synthesized with ligands N,N'-(2-methyl-2-pyridylpropan-1,3-diyl)bis(acetamide) (H2pp(ac)2)2 and NaOTf, both of which contain fully delocalized, mixed-Valence Cu(1.5)Cu( 1. 5) moieties.

TL;DR: Copper complexes of a family of pyridylmethylamide ligands HL(Ph), HL(Me3) and HL (Ph3) were synthesized and characterized and have different nuclearity owing to varying steric properties of the ligands used.

TL;DR: X-ray crystal structures reveal that for all complexes the ligands coordinate to the Cu in a monodentate fashion, and inter- or intramolecular hydrogen-bonding interactions formed between the amide NH group and either amide C=O or chloro groups stabilize these complexes in the solid state and strongly influence the structures formed.

TL;DR: A group of copper complexes supported by polydentate pyridylamide ligands H2bpda and H2ppda were synthesized and characterized to explore mixed-valence copper chemistry and the triple-decker pentanuclear cluster [CuII3CuI2(bpda)3(μ3-O)] (5) was prepared.
