Crystalline structure of zinc
WebThe crystal structure of [CuL](ClO 4) 2 showed that the Cu(II) ion is in a tetragonally distorted octahedral environment. Molecular docking studies with DNA indicated that the binding of L, [ZnLBr]ClO 4 and [CuL](ClO 4 ) 2 involved the major groove of DNA, H-bonds and Vander Waals interactions. WebTranscribed Image Text: 1.) a.) GaAs (GaAs) has the “zinc blende" crystal structure with a lattice constant of 5.653 Å. Zinc blende is the diamond cubic structure, with atoms of one type (Ga) on the vertices and faces, and atoms of the other type (As) in the internal tetrahedral sites. Determine the density of GaAs from the crystal structure.
