A germanotungstate aggregate, [H2N(CH3)2]8Na2H18[{Ni12W8/3O14-(OH)3(H2O)3}{BO(OH)2}{B2O3(OH)2}(B-α-GeW9O34)2]2·14H2O (1), with the highest nuclearity Ni cluster core among known poly(polyoxometalate) tetramers has been developed, which contains two unprecedented orderly and dense double-layered central Ni-W-O cluster cores that are further decorated by different oxo-B groups. Moreover, 1 is an efficient heterogeneous catalyst for accelerating the Knoevenagel reactions of various aldehydes with malononitrile.

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

02:42Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
