If the anions a from hexagonal close packing
WebIn a close packing, the number of octahedral voids is equal to the number of atoms and the number of tetrahedral voids is twice the number of atoms Since all the octahedral voids and half the tetrahedral voids are filled there will be one atom of B in tetrahedral void and one atom in octahedral void corresponding to each A. WebABSTRACT A novel complex, [Mn(C6H12N4)2(H2O)4][Mn(H2O)6][SO4]2·6H2O, was synthesized and hexagonal single crystals with centimeter-scale sizes were obtained by the method of solvent evaporation. It was characterized by elemental analysis, infrared spectrum, thermogravimetric analysis and X-ray single-crystal diffraction.
