Bis(tetra-n-butylammonium) (mu-N,N'-diselenium dinitride)bis[tribromopalladate(II)].
The reaction of Se(4)N(4) with (Bu(4)N)(2)[Pd(2)Br(6)] gives the title compound, (C(16)H(36)N)(2)[Pd(2)Br(6)(N(2)Se(2))], in good yield. The [Pd(2)(Se(2)N(2))Br(6)](2-) anion lies on an inversion centre, and therefore the asymmetric unit contains half a formula unit. The crystal structure confirms the coordination of the Se(2)N(2) unit to Pd through the N atoms, as previously assigned by IR spectroscopic analysis [Kelly, Slawin & Soriano-Rama (1997). J. Chem. Soc. Dalton Trans. pp. 559-562]. The title compound contains the longest Pd-N bond so far observed for such systems.
