✦ Synopsis

The mixed valent phosphoraneiminato complex [Sn 2 I 3 (NPPh 3 ) 3 ] (1) was prepared by the reaction of the tin(II) complex [SnI(NPPh 3 )] 2 with sodium in tetrahydrofuran. 1 crystallizes with two formula units of THF to form yellow, moisture sensitive single crystals, which were characterized by a crystal structure determination.

1 ´2 THF: Space group P2 1 /c, Z = 4, lattice dimensions at ±80 °C: a = 1964.5(2), b = 1766.0(2), c = 2058.6(2) pm; b = 118.33(1)°, R = 0.052. 1 forms dimeric molecules in which the tin atoms are linked by two nitrogen atoms of two (NPPh 3 ± ) groups to form a planar Sn 2 N 2 four-membered ring. The Sn IV atom is additionally coordinated by a terminal iodine atom and by a terminal (NPPh 3 ± ) group, whereas the Sn II atom is additionally coordinated by two iodine atoms forming a w trigonal-bipyramidal surrounding.
