What is 1,2‐Bis‐ N ‐[2′‐(diphenylphosphanyl)benzoyl]diaminobenzene, a New Chelating Ligand with Versatile Coordination Properties about?

## Abstract 1,2‐Bis‐__N__‐[2′‐(diphenylphosphanyl)benzoyl]diaminobenzene (dppbH; **1**) was prepared by peptidic coupling and shown to exist, in the solid state, in the form of hydrogen‐bonded dimers by single‐crystal X‐ray structure analysis. As expected, **1** reacts with [MCl~2~(cod)] (M = Pd, Pt; cod = cyclooctadiene) to form square‐planar complexes. However, in the case of palladium [PdCl~2~(dppbH)] (**2**) is obtained, while in the case of platinum [Pt(dppb)] (**3**) is formed. Thus, the nature of the metal induces a completely different coordination mode: In **2**, the dppbH ligand only coordinates through the two phosphorus atoms, while in **3** a dppb ligand, formed by deprotonation of the two amino functions in dppbH, coordinates through the two phosphorus atoms and through the two nitrogen atoms. The single‐crystal X‐ray analyses of the two square‐planar complexes reveal **2** to contain the two phosphorus atoms in a __trans__ coordination mode and **3** to contain the two phosphorus atoms in a __cis__ coordination mode.
