“…The IC 50 and MIC values were read from toxicity curves. When no growth of microorganisms had been observed in the presence of tested compounds (MIC values), the microorganisms were transferred on to appropriate fresh agar medium and incubated at 30°C for 48 h (bacteria) and at 25°C for 96 h (filamentous fungi).…”

Synthesis and characterization of 10 new 2-methylthionicotinate (2-MeSnic) Co(II) complexes, namely, reported. The characterizations were based on physicochemical and spectroscopic methods. The crystal structure of one of the complexes has been determined. In the molecular complex [Co(2-MeSnic) 2 (Me 2 fpy) 2 (H 2 O) 2 ], the Co(II) central atom, located at a symmetry centre, is octahedrally coordinated by an oxygen atom of the unidentate 2-MeSnic carboxyl group, the nitrogen atom of the pyridine ring of Me 2 fpy, a water molecule and the corresponding centrosymmetrically located atoms. Also, biological activity of the complexes against various strains of bacteria and filamentous fungi has been investigated. It is concluded that by complexation of these nicotinate derivatives their biological activities are elevated.

“…The transitions between the spin levels are observed using EMR techniques, whereas those between the ground states and the states belonging to the higher lying 2S+1 L terms or 2S+1 L J multiplets are observed using optical spectroscopy techniques. Keeping in mind the prevailing defi nitions of the crucial notions [1][2][3][4][5][6][7][8][9][10][11][12] should dispel any doubts about the incorrectness of naming the 'true' ZFS quantities as 'purportedly' the CF (LF) ones or vice versa. For the reasons exposed in [14,15,17], any idea of identifi cation of the true ZFS quantities with the true CF quantities is fundamentally wrong.…”

The interface between optical spectroscopy, electron magnetic resonance (EMR), and magnetism of transition ions forms the intricate web of interrelated notions. Major notions are the physical Hamiltonians, which include the crystal field (CF) (or equivalently ligand field (LF)) Hamiltonians, and the effective spin Hamiltonians (SH), which include the zero-field splitting (ZFS) Hamiltonians as well as to a certain extent also the notion of magnetic anisotropy (MA). Survey of recent literature has revealed that this interface, denoted CF (LF) ↔ SH (ZFS), has become dangerously entangled over the years. The same notion is referred to by three names that are not synonymous: CF (LF), SH (ZFS), and MA. In view of the strong need for systematization of nomenclature aimed at bringing order to the multitude of different Hamiltonians and the associated quantities, we have embarked on this systematization. In this article, we do an overview of our efforts aimed at providing a deeper understanding of the major intricacies occurring at the CF (LF) ↔ SH (ZFS) interface with the focus on the EMR-related problems for transition ions.
