“…Being the only distinguishing feature in the syntheses of compounds 1–4 (See syntheses in Supporting Information) the M atoms serve as the driving force of formation of certain building units (mono‐, tri‐ or hexanuclear) as opposed to simply responding to a space filling opportunity in crystal structures. In that sense this work continues our studies to reveal the role of the secondary metals in the formation of bimetallic polynuclear units …”

Crystal structures of three new uranyl compounds were solved using single crystal X‐ray diffraction and studied using FTIR spectroscopy. Although the syntheses conditions were very similar differing only in the alkaline earth metal (Mg, Ca or Sr), the resulting structures are different, containing, respectively, mono‐, tri‐ and hexanuclear metal‐containing building units. This fact proves the profound crystal‐chemical role of secondary metal atoms on the formation of crystal structures. Parameters of alkaline earth metal cations in the three newly synthesized compounds as well as in the earlier reported Ba‐containing analog are discussed in detail using Voronoi–Dirichlet polyhedra and the method of intersecting spheres. Differences in packing of building units in the four mentioned compounds, as well as inter‐ and intramolecular noncovalent interactions in their structures are reported. The results of analysis are consistent with the stereoatomic model of crystal structures.

“…The formation of one or two coordination bonds by hmta in 2 – 5 leads to differentiation of energy of CN and CH oscillators, which reflects in multiplication of the majority of hmta bands (to doublet, triplet or even quartet) in the spectra of these compounds . The splitting of bands assigned to vibrations of CC and CH bonds of carboxylate anions results from a different structural environment of each carboxylate anion in a particular compound and consequently involving them in different intermolecular interactions. Additionally, the butyrate anions in compound 4 exist in two conformations (gauche and anti), which also causes the multiplication of mentioned bands.…”

The structurally diverse coordination compounds of zinc were designed and synthesized using two types of building blocks: short‐chain carboxylate ions and hexamethylenetetraamine. They were characterized by X‐ray crystallography, infrared spectroscopy and thermal analysis. The studied compounds were used as precursors for production (via controlled thermal conversion) of zinc oxide nanoparticles. The conversion process was optimized in terms of two parameters (heating rate and maximum temperature). Such an approach, combined with proper design of the precursor structure, allows fabrication of various zinc oxide micro‐ and nanoparticles. The influence of a precursor structure and modifications of conversion parameters on size and morphology of ZnO particles were studied and discussed.

“…Using the bond‐valence approach and the following bond‐valence parameters: r 0 , r , and b equal to 1.390, 0.370, and 1.265, respectively, for O–C bonds and equal to 2.051, 0.519, and 2.465 for O–U bonds, respectively, in accordance with refs., it is easy to show that the bond‐valence sums on O atoms of carboxylate groups coordinated to uranyl ions are about 1.85 vu. Thus, the bond‐valence requirements of 2 vu for O atoms of carboxylate groups are in many instances not met by O–U and O–C bonds alone.…”

“…Assignment of absorption bands (Table ) was carried out according to refs. , , FTIR spectra of compounds with unsaturated hydrocarbon chains feature stretching and deformation vibrations of groups of atoms adjacent to C=C bonds . Very strong bands at 747 cm –1 in the spectrum of I correspond to deformation out‐of‐plane vibrations ω (=CH) and tw (=CH).…”

Two compounds with unusual architectures of uranyl complexes were synthesized and then studied by single-crystal X-ray diffraction and FTIR spectroscopy. Compound Ba 2 [UO 2 (C 3 H 5 COO) 3 ] 4 ·2C 3 H 5 COOH·7H 2 O (I) is constructed of neutral hexanuclear clusters {Ba 2 [UO 2 (C 3 H 5 COO) 3 ] 4 -(C 3 H 5 COOH) 2 (H 2 O) 4 } containing crotonate ions. Compound Sr(H 2 O) 6 {Na[UO 2 (i-C 3 H 7 COO) 3 ] 3 } (II) is constructed of anionic tetranuclear clusters {Na[UO 2 (i-C 3 H 7 COO) 3 ] 3 } 2containing isobutyrate ions. These and other examples of heteronuclear clusters imply that the alkali and alkaline-earth metal atoms in these structures are not just charge-balancing ions, but truly [a]
