“…2 H NMR spectra (resonance frequency at 45.3 MHz) were obtained from 123 K to ambient temperature on an ECA-300 spectrometer (JEOL) and a quadrupole echo pulse sequence with 2.8 μs pulse length. 23 Na magic-angle spinning (MAS) NMR spectra (resonance frequency at 132.2 MHz) were recorded on a DD2 spectrometer (Agilent Technologies) with a single pulse sequence of 2.0 μs pulse length. D 2 O and 1 M NaCl aqueous solution were used as references for the 2 H and 23 Na chemical shifts, respectively.…”

Structure and Dynamic Behavior of Sodium–Diglyme Complex in the Graphite Anode of Sodium Ion Battery by ²H Nuclear Magnetic Resonance

Cointercalation systems consisting of graphite, sodium, and some linear glycol ethers (glymes) are anticipated for use as negative electrodes in sodium ion batteries because of their superior properties such as outstanding cycle performance. We synthesized a ternary intercalation compound consisting of sodium, deuterated diglyme (diglyme-d 14 ), and graphite by a solution reaction. Then we investigated the dynamics and coordination structure of diglyme-d 14 molecules by 2 H solid-state NMR. Two diglyme molecules coordinate to each sodium ion rigidly, except for rotation of the methyl groups at low temperatures below 233 K. At room temperature, diglyme weakly coordinates to a Na ion through one oxygen atom of the ligand and rotates around the O−Na axis. The active motion of sodium−diglyme complexes is favorable for Na diffusion between graphene layers in the graphite intercalation compound.

“…2,3,[7][8][9][10] In this paper we report the results of application of new voluminous silanethiol, tris(2,6-diisopropylphenoxy)silanethiol (TDST), to the synthesis of zinc(II), cobalt(II) and nickel(II) thiolates. Similar to the Cu(I)-TDST complex described in the first communication regarding the transition metal complex with TDST, 11 all the described complexes are mononuclear and the metal ions coordinate either one or two silanethiolate ions. Each described complex incorporates additional, small ligands such as water or ethanol (zinc complexes) or ammonia (nickel and cobalt complexes).…”

Four heteroleptic complexes of nickel(ii), cobalt(ii) and zinc(ii), containing a monodentate silanethiolate ligand derived from tris(2,6-diisopropylphenoxy)silanethiol (TDST), were prepared and characterized. Nickel(ii) and cobalt(ii) complexes of the formula M(NH3)2(TDST)2 (M = Ni(ii) complex , M = Co(ii) complex ) were obtained from the respective chlorides. Zinc complexes of the general formula Zn(acac)(TDST)(L), where L = EtOH (complex ) or H2O (complex ), were obtained from zinc acetylacetonate. A single-crystal X-ray structural analysis revealed that all crystalline products are solvent adducts. The geometries of ligands in the complexes are typical: distorted tetrahedral in zinc and cobalt(ii) complexes and square planar in nickel(ii) compounds. Magnetic studies performed for Ni(ii) and Co(ii) compounds confirmed the diamagnetic character of the first complex and high-spin paramagnetic configuration of the latter. Nickel(ii) and cobalt(ii) complexes were additionally characterized by UV-Vis and IR spectroscopy. IR bands for ligands in the complexes were assigned with the help of the DFT vibrational frequency calculations.

The increasing number of metalloid clusters, synthesized in the last couple of years, gives new insights into the formation process of metals or semi-metals. Metalloid clusters of the transition metals, especially the coinage metals are thereby of particular interest and the number of structurally characterized metalloid gold clusters has in-* Prof. Dr. A. Schnepf 670 creased over the last decade. Most of these clusters are stabilized via aryl thiolate ligands. Herein, the synthesis and crystal structures of the lithium and potassium salts of the bulky SSi(SiMe 3 ) 3 ligand are presented together with the synthesis of suitable M I precursors (M = Cu, Ag, Au) for further build-up reactions to metalloid clusters.SePh with a low steric demand. As bulky ligands, like Si(SiMe 3 ) 3 (Hyp) or N(SiMe 3 ) 2 , are useful in the chemistry of nanoscaled metalloid clusters of the elements of group 13 and 14, [9] it was wondered if it is possible to use such bulky ligands also in the chemistry of metalloid clusters of coinage metals and in the following a first step into this direction is presented.
