“…2b, the silver atom is bridged to two N atoms from two distinct piperazine ligands, forming a slightly distorted linear coordination geometry around the silver(I) cation [N−Ag−N = 166.2 (2)], with the Ag−N bond lengths of 2.181(5) and 2.183(5) Å. These values are comparable to those observed in the related Silver Coordination Polymers 22,23 . The N-Ag-N skeleton gives rise to an infinite one dimensional polymeric zigzag chain of formula {[Ag (C4N2H10)] + }∞.…”

A novel silver polymer {[Ag(pip)NO3]}n was synthesized and its crystal structure is determined by single crystal X-ray diffraction analyses. The title compound crystallizes in the monoclinic space group P 21/c. Its crystal structure consists of adjacent chains of formula {[Ag(C4N2H10)] + }∞ connected through weak (N,C)−H⸱⸱⸱O interactions into the three-dimensional supramolecular framework. The DFT study is based on B3LYP/LanL2DZ of molecular structure and vibrational spectrum of this compound. Good consistency is found between the calculated and experimental frequencies.

The success of the emerging field of solid-state optical quantum information processing (QIP) critically depends on the access to resonant optical materials. Rare-earth ion (REI)-based molecular systems, whose quantum properties could be tuned taking advantage of molecular engineering strategies, are one of the systems actively pursued for the implementation of QIP schemes. Herein, we demonstrate the efficient polarization of ground-state nuclear spins—a fundamental requirement for all-optical spin initialization and addressing—in a binuclear Eu(III) complex, featuring inhomogeneously broadened 5D0 → 7F0 optical transition. At 1.4 K, long-lived spectral holes have been burnt in the transition: homogeneous linewidth (Γh) = 22 ± 1 MHz, which translates as optical coherence lifetime (T2opt) = 14.5 ± 0.7 ns, and ground-state spin population lifetime (T1spin) = 1.6 ± 0.4 s have been obtained. The results presented in this study could be a progressive step towards the realization of molecule-based coherent light-spin QIP interfaces.

“…Generally, the neutral oxime group >CNOH exhibits one active nitrogen for binding with metal ions, and therefore, it acts as a monodentate ligand with terminal coordination. However, using different substituents in the oxime carbon creates a large number of possibilities for affecting the coordination mode depending on whether the substituents have additional coordination sites, such as with pyridine − or phenol, or do not have additional coordination sites, as with the cyclohexane substituent . The location of the coordinative donor atoms in the substituent also has a major effect on the structure of the material, which can be seen, for example, in comparing coordination of 2-pyridyl oxime, which normally creates a chelating mononuclear complex, to that of 3-pyridyl oxime or 4-pyridyl oxime, which have been found to preferably lead to polymeric chain-like structures via terminal coordination .…”

6) were structurally and computationally analyzed. Weak intramolecular interactions were found to play the main role in determining the most favorable structure of the free ligands, therefore controlling the final coordination mode, and the nuclearity of the complexes. Further information on the nature of the intra-and intermolecular interactions were provided utilizing computational density functional theory calculations and topological charge density analysis according to the Quantum Theory of Atoms in Molecules. The efficient control of the structure of the complexes also results in a better control of the material properties.
