Special Issue Information

Dear Colleagues,

Metal complexes have been structurally studied for many years due to both the possibility to develop an understanding of chemical properties and their practical applications, and many different techniques have been used depending on the state and properties. The interest in metal compounds does not cease because of their topological variety and promising properties. At present, metal organic frameworks (MOF) are studied as porous materials but also due to structural conversions. Iridium complexes are synthesized because of fluorescent and phosphorescent properties being tried in OLEDs preparation. Octacyanometallates allow for the modulation of structure dimensionality, and strong magnetic coupling is observed. Chirality of the metal complexes might be important for the preparation of non-linear optics (NLO) materials. Metallic complexes are used for coatings preparation in medicine or in material science via different techniques. Obviously, there are many more metal compound classes characterized by different structure motifs and properties.

We encourage you to share your knowledge in the very broad field of metallic complexes, revealing their multiple properties and structures. The purpose of this Special Issue is to present the results of the latest works on the structural studies of metal complexes, and the potential topics include but are not limited to:

  • Synthesis methods;
  • Structure determination using single crystal XRD but also powder methods;
  • Structural end electron properties determined by different methods involved in solids studies;
  • Characterization of different properties of metal complexes—magnetic, fluorescent, porosity, conductivity, chirality;
  • Structural conversions between different crystalline forms;
  • Application of theoretical methods for determination of structures and properties of metallic complexes;
  • Synchrotron radiation application for structure determination of solids.

Influence of the Substituted Ethylenediamine Ligand on the Structure and Properties of [Cu(diamine)2Zn(NCS)4]∙Solv. Compounds
Crystals 2019, 9(12), 637; https://doi.org/10.3390/cryst9120637 - 29 Nov 2019
Abstract
In this paper, three new heterometallic compounds were described and compared with the molecular formula [Cu(pn)2Zn(NCS)4] (1), [Cu(N,N-Me2-en)2Zn(NCS)4] (2), [Cu(N-Me-en)2Zn(NCS)4 [...] Read more.
In this paper, three new heterometallic compounds were described and compared with the molecular formula [Cu(pn)2Zn(NCS)4] (1), [Cu(N,N-Me2-en)2Zn(NCS)4] (2), [Cu(N-Me-en)2Zn(NCS)4]∙½H2O (3) where pn = 1,2−diaminopropane, N,N-Me2-en = N,N‒dimethylethylenediamine and N-Me-en = N-methylethylenediamine, respectively. The compounds mentioned above were characterized by elemental analysis, infrared (IR), electronic, electron paramagnetic resonance (EPR) spectra, and magnetic studies. Crystal structures for 1 and 2 were determined by X-ray analysis. Copper(II) in these complexes adopts 4 + 2 coordination with two elongated (in 2 very long and considered as semi-coordination) Cu-S bonds. The Cu-N and Cu-S bond lengths depend on substituent position affecting steric hindrance and hence a topology of the chain. Both chains form different zigzag patterns characterized by one or two Cu-Zn distance values. Weak magnetic interaction is observed, ferromagnetic in the case of 1 and antiferromagnetic in the case of 2, due to diversity of the above structural features. Full article

Site-Preference, Electronic, Magnetic, and Half-Metal Properties of Full-Heusler Sc2VGe and a Discussion on the Uniform Strain and Tetragonal Deformation Effects

A hypothetical full-Heusler alloy, Sc2VGe, was analyzed, and the comparison between the XA and L21 structures of this alloy was studied based on first-principles calculations. We found that the L21-type structure was more stable than the XA one. Further, the electronic structures of both types of structure were also investigated based on the calculated band structures. Results show that the physical nature of L21-type Sc2VGe is metallic; however, XA-type Sc2VGe is a half-metal (HM) with 100% spin polarization. When XA-type Sc2VGe is at its equilibrium lattice parameter, its total magnetic moment is 3 μ B , and its total magnetism is mainly attributed to the V atom. The effects of uniform strain and tetragonal lattice distortion on the electronic structures and half-metallic states of XA-type Sc2VGe were also studied. All the aforementioned results indicate that XA-type Sc2VGe would be an ideal candidate for spintronics studies, such as spin generation and injection. Full article
