 Title    Dichlorcyclopropenon als stabiler Komplexligand Die Kristallstruktur von [NbOCl 3 -OC 3 Cl 2 ] 4 Dichlorocyclopropenone as Stable Complex Ligand The Crystal Structure of [NbOCI 3 * OC 3 Cl 2 ] 4  
 Abstract    The reaction of tetrachlorocyclopropene with NbOCl, yields NbCl 5 • OC 3 Cl 2 (1); 1 is also formed by partial hydrolysis of C 3 Cl 3 + NbCl 6 ~ (2), which is prepared from C 3 C1 4 and NbCl s . [NbOCl 3 • OC 3 Cl : ] 4 (3) was obtained by hydrolysis of 1 in form of pale-yellow, moisture sensitive, non-explosive crystals, and characterized by its IR spectrum and an X-ray crystal structure deter-mination (1871 independent observed reflexions, R = 0.048). Crystal data: space group P 1. Z = 2. a = 993.7(4), b = 1090.5(5). c = 1097.4(3) pm, a = 69.51(3), ß = 70.47(3), y = 66.51(4)° (at — 17 °C). 3 consists of centrosymmetrical tetramers; the four Nb atoms form a square and are linked via almost linear oxo groups with alternating short and long NbO bonds with mean bond lengths of 175 and 208 pm. In trans position of each of the short NbO bonds a dichlorocyclo-propenone molecule is attached via its oxygen atom with an NbO distance of 223 pm.
