Abstract
The molecular structures of two dysprosium complexes of donor-functionalized pentadienyl ligands are described. Electronic structure calculations reveal that the W-shaped pentadienyl ligand strongly influences the orientation of the main magnetic axis of the ground Kramers doublets in both complexes.

Abstract
Previously, hydridotris(pyrazolyl)borate (Tp) Ru(II) alkyl and aryl complexes of the type TpRu(L)(NCMe)R (R = methyl or aryl; L = charge-neutral two-electron donating ligand) were demonstrated to activate aromatic C-H bonds. To determine the impact of replacing the anionic Tp ligand with charge-neutral poly(pyrazolyl)alkane ligands, [(C(pz)4)Ru(P(OCH2)3CEt)(NCMe)Me][BAr'4] (pz = pyrazolyl, BAr'4 = tetrakis[3,5-bis(trifluoromethyl)phenyl]borate) was prepared. Heating a C6D6 solution of [(C(pz)4)Ru(P(OCH2)3CEt)(NCMe)Me][BAr'4] with 1 equiv of NCMe resulted in C-H activation of the 5-position of a pyrazolyl ring to yield [(κ(3)-(N,C(5),N)C(pz)4)Ru(P(OCH2)3CEt)(NCMe)2][BAr'4] and CH4. Intramolecular C-H activation of the 5-position of a pyrazolyl ring also occurred when (η(6)-p-cymene)Ru(P(OCH2)3CEt)(Br)Ph was heated in the presence of C(pz)4 to yield [(κ(3)-N,C(5),N)C(pz)4]Ru(P(OCH2)3CEt)(NCMe)Br and C6H6. Density functional theory calculations revealed that the different reactivities of TpRu(P(OCH2)3CEt)(NCMe)R and [(C(pz)4)Ru(P(OCH2)3CEt)(NCMe)Me][BAr'4] result from the stronger binding of the Tp pyrazolyl rings to Ru(II) compared to that of C(pz)4.
