摘要
The structures of pentaphenylantimony (I), its solvates with benzene (II) and dioxane (III), and penta(p-tolyl)antimony (IV) are solved by X-ray diffraction (XRD) (CIF files CCDC nos. 2124594, 2121835, 2124972, and 2124962, respectively). The following parameters are determined from the XRD data: crystals of Ph5Sb (I): a = 10.286(3), b = 10.510(4), c = 13.590(4) angstrom; alpha = 68.29(2)degrees, beta = 79.364(14)degrees, gamma = 61.272(12)degrees; V = 1196.9(7) angstrom(3); Z = 2; solvate Ph5Sb center dot 0.5PhH (II): a = 13.165(11), b = 14.394(16), c = 15.193(13) angstrom; alpha = 90.22(3)degrees, beta = 113.71(2)degrees, gamma = 94.23(5)degrees; V = 2627(4) angstrom(3); Z = 2; solvate Ph5Sb center dot 0.5C(4)H(8)O(2) (III): a = 10.451(5), b = 10.462(4), c = 13.323(5) angstrom; alpha = 75.647(11)degrees, beta = 69.648(19)degrees, gamma = 86.300(19)degrees; V = 1322.8(9) angstrom(3); Z = 2; and p-Tol(5)Sb (IV): b = 12.084(7), c = 17.009(6) angstrom; beta = 102.934(14)degrees; V = 2899(2) angstrom(3); Z = 4. The antimony atoms in solvates II and III have a distorted trigonal bipyramidal coordination.
