Crystal structure of a palladium(II) complex containing the wide bite-angle bis­(selenium) ligand, cis-[((t)BuNH)(Se)P(μ-N(t)Bu)(2)P(Se)(NH(t)Bu)]

A palladium(II) complex {systematic name: dichlorido[1,3-di-tert-butyl-2,4-bis(tert-butylamino)-1,3,2λ(5),4λ(5)-diazadiphosphetidine-2,4-diselone-κ(2) Se,Se′]pal­ladium(II)}, cis-[PdCl(2){I}], (II), containing a bis­(selenium) ligand based on cyclo­diphosph(V)azane, cis-[((t)BuNH)(Se)P(μ-N(t)Bu)(2)P(Se)(NH(t)Bu)], (I), has been synthesized and structurally characterized. The crystal structure of complex II reveals that the ligand chelates through selenium donors with the natural bite-angle of 110.54 (1)° and a Pd—Se bond distance of 2.444 (1) Å. The coordination around Pd(II) shows a slightly distorted square-planar geometry, as indicated by the angle between the [PdCl(2)] and [PdSe(2)] planes of 5.92 (3)°. In the crystal, the mol­ecules are inter­linked through weak N—H⋯Cl and C—H⋯Cl hydrogen-bonding inter­actions.
