| Synthese und Kristallstruktur von (PPh4)2[Mo2(02C—Ph)4Cl4] * 2 CH2C12, einem Komplex mit Mo=Mo-Bindung Synthesis and Crystal Structure of (PPh4 )2 [Mo2 (0 2 C —Ph)4 Cl4] -2 CH 2 C12, a Complex with M o=M o Bonding  | | | | Abstract
| The title com pound has been prepared from (PPh4)2[M o2(0 2C —Ph)4Cl2] and CC14 in C H 2C12 solution as moisture sensitive crystals, which are black in reflexion and yellow in transmission. (PPh4)2[M o2(0 2C —Ph)4Cl4] • 2 C H 2C12 was characterized by a X-ray crystal structure determ ination (7873 observed independent reflexions, R = 0.048). It crystallizes in the space group P 1 with one formula unit in the unit cell; the lattice constants are a = 1186.4; b = 1404.0; c = 1451.0 pm; a = 61.98°; ß = 78.91°; y = 78.26°. The structure consists o f PPh4® ions, C H 2C12 m olecules and centrosym m etric anions [M o2(0 2C —Ph)4Cl4]20 containing a molybdenum d3d3 unit with a relatively long M o = M o bond o f 249.6 pm. The M o= M o group is spanned in a chelate manner by four O atoms of two benzoate groups and by two further single O atoms o f two further benzoate groups. Two terminal Cl atom s on each Mo atom com plete the pentagonal bipyramidal coordination spheres about the Mo atoms. | | | |
