Tetra-Schiff bases derived from (chiral) bis-salphen ligand scaffolds furnish, upon metalation with appropriate metal reagents, their multinuclear structures with associated Zn(OAc)(2) or Zn(OH)(2) fragments. The tendency of retaining these salts was investigated using four different (chiral) bis-salphen scaffolds. The presence of the additional Zn ions was supported by NMR studies, mass determ...

Multinuclear solid-state nuclear magnetic resonance (NMR) techniques are useful for structural investigations of insoluble and amorphous natural products, have been gaining importance in coal chemistry. In addition to iron ore, is essential as steel raw material, but the physical properties remained unclear. Valuable information on coal, such cluster size, chemical distribution various function...

Using a novel strategy, tertiary phosphines based on single atom peri-bridged acenaphthenes were prepared and characterized by multinuclear NMR and by X-ray diffraction.

A simple, one-step synthesis of multinuclear Lewis acids can be driven with high selectivity towards either macrocyclic or polymeric arrays by appropriate choice of backbone framework.

The incidence of binuclear, trinuclear, quadrinuclear, and multinuclear (five or more nuclei per cell) in both tumors was estimated. Asynchronous DNA synthesis and asynchro nous mitosis were frequent in the binuclear and trinuclear pools in the first patient and in all the cell pools in the second patient. Cytogenetic studies demonstrated aneuploidy in the tumor cells removed from both patients...

This study investigated the effect of reaction time (minutes to months) on the surface coordination environment of Ni sorbed onto pyrophyllite using XAFS. The data suggest the appearance of multinuclear Ni complexes after a reaction time of minutes. As reaction time !>rogresses, these multinuclear Ni complexes increased in size «NNi-Ni 1.4-4.5). Ni-Ni bond distances (2.99-3.03 A) were similar t...

The encapsulation of cisplatin by cucurbit[7]uril (Q[7]) and multinuclear platinum complexes linked via a 4,4'-dipyrazolylmethane (dpzm) ligand by Q[7] and cucurbit[8]uril (Q[8]) has been studied by NMR spectroscopy and molecular modelling. The NMR studies suggest that some cisplatin binds in the cucurbituril cavity, while cis-[PtCl(NH3)2(H2O)]+ only binds at the portals. Alternatively, the dpz...

An analysis of the electron-nuclear entanglement structure in solid-state defect spins leads to protocols for generating multinuclear entanglement, opening full potential nuclear spin memories quantum networks.
