Popis:	The nitrido complexes [MoN(S 2 CNR 2 ) 3 ] (R 2  Me 2 , Et 2 ) and [ReN)S 2 CNR 2)2 -(PMe 2 Ph) n ] (R 2  Me 2 ; Et 2 ; n  0, 1) react with halides R′X (R′  PhCO, PhSO 2 , 2,4-(NO 2)2 C 6 H 3 , 2,4-(NO 2)2 C 6 H 3 S; X  Cl, R′  Me, X  I), [R′3 O ]BF 4 (R′  Me, Et) or [Ph 3 C]BF 4 to give the imido complexes [Mo(NR′)(S 2 CNR 2 ) 3 ]+ and [Re(NR′)(S 2 CNR 2 ) 2 (PME 2 Ph) n ] (R′  Me, Et, Ph 3 C + , PhSO 2 , PhCO, 2,4(O 2 N) 2 -C 6 H 3 , 2,4-(O 2 N) 2 C 6 H 3 S); the X-ray crystal structures of [Mo(NCPh 3 )(S 2 -CNMe 2 )3]BF 4 and [Mo(NSO 2 Ph)(S 2 CNMe 2 )3]PF 6 have been determined. Both complexes have approximately pentagonal bipyramidal geometries although the NSO 2 Ph complex is more distorted. The NCPh 3 and NSO 2 Ph complexes have MoNC and MoNS angles of 175.1(5) ° and 161.3(13)° and MoN distances of 1.731(2) and 1.70(2)A, respectively.
