⁸¹Br NQR and ¹H NMR of Ethylammonium Tetrabromomercurate (II) (C₂H₅NH₃)2HgBr₄: Phase Transition and Molecular Motion

Antimony-121 Mössbauer spectra for hypervalent pentacoordinate antimony compounds having Sb-transition metal bond [Rf 2 SbMCp(CO) n {RfH = o-C 6 H 4 C(CF 3 ) 2 OH - , M = Fe, Ru, Cr,Mo, W}, Rf 2 SbFeCp(CO)PPh 3 , Rf 2 SbFeCp(dppe)] and closely related compounds Rf 2 SbTol (Tol = p-CH 3 C 6 H 4 ), Rf 2 SbX (X = Cl, Br) are described. The strong -donor power of the metal fragments is demonstrated by theM¨ossbauer parameters. The -donor power decreases in the order FeCp(dppe) > FeCp(CO)PPh 3 > FeCp(CO) 2 > RuCp(CO) 2 > CrCp(CO) 3 > MoCp(CO) 3 > WCp(CO) 3 ≫Tol. The essential trends in the molecular structure and the Berry pseudorotation are interpreted by this order. In addition, the e 2 qQ values for 32 hypervalent antimony compounds are successfully calculated using the additivity model for the e 2 qQ value. A unique electronic feature for Rf 2 SbX is clarified through the calculation

About this journal

Objective
A Journal of Physical Sciences: Zeitschrift für Naturforschung A (ZNA) is an international scientific journal which publishes original research papers from all areas of experimental and theoretical physics. Authors are encouraged to pay particular attention to a clear exposition of their respective subject, addressing a wide readership. In accordance with the name of our journal, which means “Journal for Natural Sciences”, manuscripts submitted to ZNA should have a tangible connection to actual physical phenomena. In particular, we welcome experiment-oriented contributions.

Manuscripts considered for publication in A Journal of Physical Sciences: Zeitschrift für Naturforschung A undergo high-level refereeing. Mere formal correctness of a paper is not sufficient for its acceptance. Moreover, articles reporting a merely marginal extension of already existing knowledge are considered unsatisfactory. Instead, the key quality a publication in A Journal of Physical Sciences: Zeitschrift für Naturforschung A should possess is that it makes a genuine contribution to the advancement of its topic.

Topics

Atomic, Molecular & Chemical Physics
Dynamical Systems & Nonlinear Phenomena
Gravitation & Cosmology
Hydrodynamics
Quantum Theory
Solid State Physics & Materials Science
Thermodynamics & Statistical Physics

Article formats
Original research articles, research notes, letters and review articles from all areas of theoretical and experimental physics
