Front Cover: Bond Strength of a Diatomic Acceptor Ligand: A Reliable Measure of Its Antibond Occupation and Its Charge? (Eur. J. Inorg. Chem. 32/2022)

Abstract: The Front Cover shows, pictorially as the collapse of a house of cards, the repeal of the customary correlation of a nitrosyl ligand's charge and the strength of its N−O bond. Isomeric couples comprising both a linear and a bent MNO moiety show, in fact, a weaker bond of the bent form in terms of a markedly red‐shifted NO stretch. However, the charge of the NO group is not a function of the bond strength. Hence, the assignment of an 1NO− to a bent‐bonded nitrosyl and NO+ to a linear‐bonded one is unjustified a… Show more

“…First, the charge of the nitrosyl ligands is almost the same for both forms. Second, the local force constants k a indicate a bond weakening of both the Pd−N and the N−O bond in the bent form as is known from {CoNO} 8 and {RuNO} 6 species [23d] …”

“…Hence, the GS/MS transition of 1 is a non‐DCD event which lacks the DCD‐typical charge/bond‐strength correlation of an acceptor ligand. The physical origin of the observed redshift, lateral electrostatic influence on bending, is addressed in a separate work [22] …”

“…schen Ursache der beobachteten Rotverschiebung, nämlich lateraler elektrostatischer Einfluss bei der Abwinkelung, wird in einer eigenen Arbeit adressiert. [22] Der TS lohnt eine nähere Betrachtung. Entgegen der üblichen Zuordnung der Ladungen in linearen und gewinkelten MNO-Funktionen ändern sich im Verlauf des linear/gewinkelt-Übergangs in 1 die Ladungen der Nitrosylliganden nicht signifikant.…”

“…Es wird deutlich, dass die GS/MS‐Umwandlung in 1 kein DCD‐Ereignis ist und daher der DCD‐typischen Ladungs–Bindungsstärke‐Beziehung die Grundlage fehlt.
