In an attempt to prepare the tris(selenoureato)gallium(III) complex [Ga(4-O2NC6H4C(O)NC(Se)NEt2)3] from the reaction of the nitro-substituted acylselenourea 4-O2NC6H4C(O)NHC(Se)NEt2 with [Ga(NO3)3] in EtOH we obtained a crystalline compound from a CH2Cl2 solution which was identified as the bis(selenoureato)gallium(III)chlorido complex [GaCl(4-O2NC6H4C(O)NC(Se)NEt2)2] by single-crystal X-ray diffraction. This compound is a rare example of a metal complex containing chelating selenoureato ligands in a trans arrangement.
