“…Actually this structure displays some covalent-like bonding interactions within the gallium sublattice and more particularly between gallium and platinum atoms. The overlap populations calculated by CASTEP are 0.55 for PteGa(1) (2.598 Å) and also for PteGa(2) (2.569 Å) while they are 0.26 (2.612 Å) and 0.37 (2.885 Å) for Ga(2)eGa (2). Although the PtePt distance (2.776 Å) is in the order of that in pure metal (2.77 Å, CN 12), the calculated overlap population is weak, 0.05 against 0.50 in the metal.…”
