“…The coordination chemistry of 1,4,7-triazacyclononane (TACN) has been extensively studied for its applications in the simulation of metalloenzymes and metalloproteins (Chaudhury et al, 1985;Deal et al, 1996;Hegg & Burstyn, 1995;Hegg et al, 1997;Lin et al, 2001;Williams et al, 1999) as well as in constructing molecule-based magnetic materials (Berseth et al, 2000;Cheng et al, 2004;Poganiuch et al, 1991). In general, TACN ligand can form stable sandwich complexes with many transition metals (Stranger et al, 1992;Zompa & Margulis, 1978) or functions as a terminal chelator for the assembly of binuclear/polynuclear species and coordination polymers supported by bridging ligands (Bencini et al, 1990;Wang et al, 2005;Wang et al, 2003). In this paper, a half-sandwich type Ni II complex with TACN has been synthesized and characterized.…”

In the title half-sandwich compound, [Ni(C6H15N3)(H2O)3]Br(NO3), the central NiII ion, lying on a threefold rotation axis, is six-coordinated by three amine N atoms from the face-capping triaza macrocycle and three water O atoms in a slightly distorted octahedral geometry. In the crystal, O—H⋯O hydrogen bonding and weak O—H⋯Br interactions associate the NiII cations and the counter-ions into a three-dimensional supramolecular network.

Binuclear Nickel(II) Complexes Based on Bridging Oxalate and Pseudohalides as Peripheral Ligands: Synthesis, Crystal Structure, DFT Calculations and Magnetic Properties of [{Ni(X)(dien)}2(μ-ox)]·nH2O Complexes (X = N3−, NCS−,n= 0; NCO−,n= 1)

Nickel(II) molecular complexes were obtained by water displacement reactions of [{Ni(dien)(H2O)}2(μ‐ox)]Cl2 and the corresponding pseudohalide. The three nickel(II) compounds [{Ni(N3)(dien)}2(μ‐ox)] (1), [{Ni(NCO)(dien)}2(μ‐ox)] · H2O (2) and [{Ni(NCS)(dien)}2(μ‐ox)] (3) are almost isostructural. The structure determinations reveal the presence of a binuclear complex with C2h symmetry, where the oxalate ligand is coordinated in a bis(bidentate) fashion to the twofold related nickel atoms. The distorted octahedral environment of each nickel atom is completed by the three nitrogen atoms of the diethylenetriamine ligand in a fac arrangement and one nitrogen atom from a pseudohalide ligand. Magnetic susceptibility data in the temperature range 4.2−300 K shows intramolecular antiferromagnetic coupling.
