Resumo

In the present work, the influence of the nature of the solvate molecules and N-donor ligands on the structures of the benzoate–pentafluorobenzoate europium complexes was investigated. It was established that the reaction of europium benzoate (bz) and pentafluorobenzoate (pfb) with 1,10-phenanthroline (phen) in acetonitrile in the presence of toluene, o-xylene, or dichloromethane leads to the formation of compounds [Eu2(phen)2(pfb)4(bz)2]·4C6H5CH3 (I), [Eu2(phen)2(pfb)4(bz)2]·4C6H4(CH3)2 (II), and [Eu2(phen)2(pfb)4 (bz)2]·2.898CH2Cl2 (III), respectively, which possess similar structures. Using quinoline (quin) as the N-donor ligand, mixed-carboxylate coordination polymer crystals [Eu(H₂O)(pfb)2(bz)]n·2n(quin) (IV) were obtained in good yield. The synthesized compounds were characterized by single-crystal X-ray diffraction, IR spectroscopy, and CHN elemental analysis. Non-covalent interactions were analyzed by Hirshfeld surface analysis.

New Stannandiamines Comprising Photoactive Fragments
Demkin A., Latushko E., Savkov B., Sukhikh T., Konchenko S.
Resumo

The reactions of dibutyltin dichloride with potassium amides KNH-pap, KNH-4pbt, and KNH-2pbt (pap = 4-(phenylazo)phenyl; 4pbt = 1,3-benzothiazol-2-yl-4-phenyl; 2pbt = 1,3-benzothiazol-2-yl-2-phenyl) were studied. It was found that in the case of KNH-pap and KNH-4pbt, the only products formed were stannanediamines nBu2Sn(NH-pap)2 (I) and nBu2Sn(NH-4pbt)2 (II). However, in the case of KNH-2pbt, an inseparable mixture of stannanediamine nBu2Sn(NH-2pbt)2 ( III) and cyclodistannadiazane [nBu2Sn(N-2pbt)]2 (IV) was obtained. The molecular structures of compounds I–IV were determined by single-crystal X-ray diffraction (SCXRD) analysis of the crystalline phases I · 0.5C7H8, II · 0.5THF, III, and IV (CCDC No 2367378 (I · 0.5C7H8), 2367379 (II · 0.5THF), 2367380 (III), and 2367378 (IV)).

Synthesis and Luminescent Properties of the Carbonyl-Isonitrile Re(I) Complex Based on Menthol-Modified Phenanthroline
Davydova M., Agafontsev A., Yudin V., Rakhmanova M., Artem’ev A.
Resumo

A carbonyl-isonitrile complex of [Re(CO)₃(L)(m-XylylNC)]OTf formulation (m-XylylNC – 2,6-dimethyl-phenyl isocyanide) was synthesized based on the 1,10-phenanthroline ligand (L) containing a menthol fragment (MtO) in position 2. The Re(I) atom in the cationic part of this complex has a distorted octahedral environment formed by the N,N′-chelate ligand L, one isonitrile ligand, and three CO ligands. The resulting compound exhibits bright green phosphorescence at room temperature in both the solid state and solution, with quantum yields of 15% and 10%, respectively.

Synthesis and Structure of Iron(II) Complex Compounds with 1-Methyl-2-Pyridine-2-yl-1Н- and 1-Methyl-2-Phenyliminomethyl-1Н-Benzimidazoles and Boron Cluster Anions [BnHn]²⁻ (n = 10, 12)
Avdeeva V., Kubasov A., Nikiforova S., Belousova O., Malinina E., Kuznetsov N.
Resumo

The paper studies reactions of iron(II) complexation with benzimidazole derivatives L (L1 = C13N3H11, L2 = C15N3H13) in the presence of salts of boron cluster anions [BnHn]2– (n = 10, 12). The obtained complex compounds of the general formula [FeL3][BnHn] are characterized by elemental analysis and IR spectroscopy. The structure of complex [FeL13][B10H10] is determined by single-crystal X-ray diffraction (CCDС № 2432134). The distorted octahedral environment of the Fe atom is formed by the imidazole and pyridine N atoms of three L1 molecules. In the crystal, the [FeL13]2+ complex has a meridional configuration. The Fe–N bond lengths for imidazolium nitrogen atoms are in the range of 1.954(8)–1.980(6) Å, and for pyridine nitrogen atoms 1.977(7)–2.011(8) Å.

New Manganese(II) Coordination Compounds with 4-{[(1H-Pyrrol-2-yl)methylene]amino}-4H-1,2,4-triazole
Bovkunov A., Bazhina E., Shmelev M., Gogoleva N., Anisimov A., Kottsov S., Babeshkin K., Efimov N., Metlin M., Taydakov I., Fetisov L., Svyatogorova A., Zubenko A., Kiskin M., Eremenko I.
Resumo

The reaction of manganese(II) chloride with the azomethine ligand 4-{[(1H-pyrrol-2-yl)methylene]amino}-4H-1,2,4-triazole (HPyrtrz) yielded crystals of the 1D-polymeric compound [MnII(HPyrtrz)(H2O)Cl2]n (I). The addition of the co-ligand 1,10-phenanthroline (phen) to the synthesis of I was found to led to the sequential crystallization of two products, namely, the 1D-polymeric compound [MnII(Phen)Cl2]n (II) and the mononuclear complex [MnII(phen)2Cl2] HPyrtrz (II). Complex III was found to be isolated as a single product in the reaction of compound I with phen or in the reaction of the known complex [MnII(Phen)2Cl2] with HPyrtrz, respectively. The crystal structures of compounds I-III were determined by single-crystal X-ray diffraction (CIF files CCDC № 2339139 (I), № 2344064 (II), № 2339140 (III)). For I and III, antimicrobial activity was studied against E. coli and S. aureus bacterial strains and Penicillium italicum Wehmer mold. According to the temperature dependence of magnetic susceptibility, antiferromagnetic exchange interactions between Mn2+ ions (J = –2.69 cm–1) are realized in compound I. Spectral-luminescent studies showed that HPyrtrz, I and III exhibit blue luminescence in the solid phase.
