Crystal structure of a palladium(II) complex containing the wide bite-angle bis­(selenium) ligand cis-(tBuNH)(Se)P(μ-NtBu)2P(Se)(NHtBu)

摘要

A palladium(II) complex {systematic name: dichlorido[1,3-di-tert-butyl-2,4-bis(tert-butylamino)-1,3,2λ⁵,4λ⁵-diazadiphosphetidine-2,4-diselone-κ² Se,Se′]pal­ladium(II)}, cis-[PdCl2{>I}], (>II), containing a bis­(selenium) ligand based on cyclo­diphosph(V)azane, cis-[(^tBuNH)(Se)P(μ-N^tBu)2P(Se)(NH^tBu)], (>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 [PdCl2] and [PdSe2] planes of 5.92 (3)°. In the crystal, the mol­ecules are inter­linked through weak N—H⋯Cl and C—H⋯Cl hydrogen-bonding inter­actions.
