N-benzoyl-N',N'-dibutylselenourea and its palladium(II) complex.
The crystal and molecular structures of N-benzoyl-N',N'-dibutylselenourea (HL), C16H24N2OSe, and the corresponding complex bis(N-benzoyl-N',N'-dibutylselenoureato-kappa(2)Se,O)palladium(II), [Pd(C16H23N2OSe)2], are reported. The selenourea molecule is characterized by intermolecular hydrogen bonds between the selenoamidic H atom and the Se atom of a neighbouring molecule forming a dimer, presumably as a consequence of resonance-assisted hydrogen bonding or pi-bonding co-operativity. A second dimeric hydrogen bond is also described. In the palladium complex, the typical square-planar coordination characteristic of such ligands results in a cis-[Pd(L-Se,O)2] complex.
