Coordination number, the number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbours in a complex or coordination compound or in a crystal. Thus the metal atom has coordination number 8 in the coordination complexes [Mo
The high coordination number of Eu3+-L not only benefits to sufficient sensitization of the Eu3+ ion based on the antenna effect, but also prevents luminescent quenching caused by the infiltration of water molecule, thus endowing the lanthanide coordination polymer with characteristic emission color...
Ultrasonic absorption data for 0.200 M erbium chloride and nitrate as a function of solvent composition in aqueous dimethylformamide are interpreted in terms of a coordination number change being present in both salt systems between 0.1 and 0.2 water mole fraction. Erbium chloride undergoes a second ...
Coordination number (CN) is discussed from a geometrical point of view. Two models for the determination of CN 8 to 11 have been developed and tested with good results on 78 polyhedra consisting of alkali/alkaline earth metals as central atoms and halogen atoms/water oxygens as ligands. In ...
This finding allowed us to examine the developmental competence of oocytes matured in vivo (i.e., ovulation) from XY females and compare the results with those matured in vitro. Figure 1 eCG-dosage dependent ovulation of oocytes from XX and XY females. The number of ovulated oocytes was ...
Synthesis and characterization of manganese complexes containing a synthetic macrocyclic ligand A number of manganese(II) and -(III) complexes with the uncharged 14-membered macrocyclic ligand, meso-5,5,7,-12,12,14-hexamethyl-1,4,8,11-tetraazacyclotet... PS Bryan,JC Dabrowiak - 《...
Stereostructural behaviour of N–N atropisomers: Two conglomerate crystallisations and a crystallisation-induced deracemisation The solid state behaviour of a number of compounds which show hindered rotation around an N–N bond, in some cases leading to axial chirality is described... RJ Arthur,MP...
and sp3hybridization ofvalence electronsof the carbon atom leads to a limited number of possible geometries in organic compounds, namely, linear, trigonal-planar, and tetrahedral. One asymmetrical sp3hybridized carbon atom generates one pair ofenantiomers, while an asymmetrical sp3d2or d2sp3hybridized...
Scientific Reports volume 11, Article number: 21974 (2021) Cite this article 1768 Accesses 4 Citations Metrics details Abstract Joint operation of the Longyangxia and Liujiaxia reservoirs (Long-Liu operation) is of great significance for water and sediment regulation in the Yellow River. The water...
Here, we successfully fabricate fully exposed Pt3 clusters on the defective nanodiamond@graphene (ND@G) by the assistance of atomically dispersed Sn promoters, and correlated the n-butane direct dehydrogenation (DDH) activity with the average coordination number (CN) of Pt-Pt bond in Pt NP, Pt...
