Mononuclear structures

Formula HfCR MW 320.30 tetrahedral and mononuclear structure in gas phase, halide bridging polymeric structure in solid phase. 

The above description of the mononuclear structures of the copper(II) ion presupposes that the structures are all determined at room temperature. If they were determined at a... 

There were 11 mononuclear structures extracted from the CSD with geometric parameters matching the established criteria for significant Sn... tt interactions their chemical structures are shown in Schemes 3.9.3 and 3.9.4. 

Electron spin resonance studies of the structural features of binuclear copper carboxylates suggest that the magnetic properties of biologically important molecules which contain copper may be better understood with this spectrophotometric technique [728]. Indeed, Greenaway, Norris and Sorenson used electron spin resonance to show that the copper complex of 3,5-diisopropylsalicylic acid is actually isolated as a binuclear complex, Cu(II)2(3,5-DIPS)4(H20)2, as opposed to the mononuclear structure, Cu(II)(3,5-DIPS)2, used throughout this manuscript, and organic solvates of this complex are also binuclear [729]. Electron spin resonance has also been used to study the orientation and mobility of Cu(II)[3-ethoxy-2-oxobutyralde-hyde bis(dimethylthiosemicarbazone)] in a bilayer lipid vesicle [730]. 

In microencapsulation technology, different particle structures as well as different processes are possible [137,138]. The particle may have a mononuclear structure, consisting of a core and a shell, or polynuclear structure, where many cores are encapsulated in one shell. Finally, the particles may have a matrix structure, where the core material is homogeneously distributed in a shell material. A possible disadvantage of such a delivery system is that parts of the core substance may not be completely covered by the shell material (especially with high payloads). 

Fig. 11 A schematic representation of a a one-dimensional structure of reported simple phosphate Ca complexes, b a zigzag structure of less bulky phosphate Ca complex, c a cyclic octanuclear structure of the same less bulky phosphate Ca complex, d a hex-anuclear structure of the less bulky phosphate Na(l) complex, and e a mononuclear structure of an extremely bulky phosphate Ca complex with unsymmetric ligand coordination. White and black boxes represent organic phosphate and other ligands (water and methanol), respectively. Circle refers to metal ion...
