X‑ray Absorption Spectroscopy Proves the Trigonal-Planar Sulfur-Only Coordination of Copper(I) with High-Affinity Tripodal Pseudopeptides

A series of tripodal ligands L derived from nitrilotriacetic acid (NTA) and extended by three converging metal-binding cysteine chains were previously found to bind selectively copper(I) both in vitro and in vivo. The ligands L 1 (ester) and L 2 (amide) were demonstrated to form copper(I) species wi...
