The resultant complexes were investigated for their magnetic properties in order to elucidate the impact of modification of the coordinating P−O bond environment either by increasing steric bulk and/or introduction of a third P−N bond at the central phosphorus atom. Magnetic studies revealed substantial energy barriers ( U eff ) of 640 K and 491 K for Dy compounds 1 and 2 , respectively, rendering them as some of the best‐performing air‐stable SIMs amongst the class of SIMs with D 5h symmetry. Compounds 1 and 2 exhibit magnetization blocking ( T B ) at 6.5 K and 6 K, respectively, at a sweep rate of 20 Oe/s. Compound 1 benefits from increased lattice intermetallic distances due to bulky adamantyl substituent, but exhibits a significant deviation from linear axial (P)O−Dy−O(P) geometry (173.7(1)°). In addition to the deviation from linearity, the incorporation of a bulky adamantane (or carbazole) ligand in complex 1 (or 2 ) was found to result in relatively strong Dy…H−C agostic interactions, with distances of 3.698 Å (3.376 Å). These interactions are expected to induce transverse anisotropy. Ab initio CASSCF/RASSI‐SO/SINGLE_ANISO calculations offer valuable insights into the dynamics of magnetic relaxation and the impact of axial bulkiness on the anisotropy of D 5h systems. Beyond highlighting the crucial role of crystal field and symmetry in achieving high‐temperature SIMs, this study also explores how the secondary coordination sphere can be engineered to create novel SIMs.Indian Institute of Technology Delhi https://doi.org/10.13039/501100007488Deutsche Forschungsgemeinschaft https://doi.org/10.13039/501100001659Science and Engineering Research Board https://doi.org/10.13039/50110000184

Tight bounds on parallel list marking
No full textn)-PRAM, when only the location of the head of the list is initially known. Under the assumption that memory cells containing list nodes bear no distinctive tags distinguishing them from other cells, we establish an OHgr (min{ell, n/p}) randomized lower bound for ell-node lists and present a deterministic algorithm whose running time is within a logarithmic additive term of this bound. In the case where list cells are tagged in a way that differentiates them from other cells, we establish a tight theta (min {ell,ell/p + radic(n/p) log n }) bound for randomized algorithms
