disorder in main residue; R factor = 0.027; wR factor = 0.079; data-to-parameter ratio = 15.1. In the title complex, [Ni(C2N3)2(C9H24N4)], the Ni II atom is coordinated in a distorted octahedral geometry by one tris(3-aminopropyl)amine (trisapa) ligand and two dicyanamide (dca) ligands [one of them disordered in a 0.681 (19):0319 (19) ratio]. Intermolecular N—H N hydrogen bonds involving the N atoms of the dca anions and the trisapa amine H atoms result in the formation of a three-dimensional network
