| Abstract: The empirical formula for calculating the distance D between the quad-bridging-capping atom E and the plane consisting of metal atoms M, D=(［0.92(RM+RE)］2-2R2M)1/2, has been proposed, which can decide if there exists the metal-metal bond by comparing D with experimental values d. The relationship between RM (metallic radii) and RE (covalent radii of quad-bridging-capping atom) to be satisfied in forming the tetranuclear-planar clusters ［M4E2］ and ［M4E］ are RE≥1/2RM and RE≥0.414RM, respectively. |
