| Kristallstruktur von [MoC12(N S N )-2TH F]2; einem Metallaheterocyclus mit der NSN4 -Einheit Crystal Structure of [MoC12(N S N )-2T H F ]2; a M etallaheterocycle with the NSN4-Unit  | | | | Abstract
| The chlorothionitrene complex [Cl4M o(NSCl)]2 reacts with N ,N,N '-tris(trim ethylsilyl)benzam idine in T H F solution to form the heterocyclic complex [MoC12(NSN) ■ 2T H F ]2, which contains the [NSN]4-unit. The com pound is characterized by IR spectro scopy and by an X-ray structure determ ination (Space group P2,/c, Z = 2, 1504 observed unique re flexions, R = 0.044. Lattice dim ensions at 19 °C: a = 1176.0(1), b = 1108.6(4), c = 1227.3(3) pm, ß = 118.25(1)°). The com pound forms centrosym m etric molecules [(TH F)2C12M o(NSN)2MoC12(T H F)2], in which the molybdenum atoms are members of a nearly planar M o(NSN)2Mo eight-m em bered ring with bond lengths MoN 180.2 and 175.2 pm; NS 157.5 and 160.6 pm; the bond angle NSN is 108.3°, corresponding to a NSN4-unit. | | | |
