چکیده
The title complex, [Hf(C29H41N2)Cl3], was synthesized from HfCl4 and HC[C(Me)N( (i) Pr2C6H3)]2Li(Et2O) in toluene. The structure is isotypic with those of Ti(IV) and Zr(IV) complexes reported previously [Nikiforov et al. (2007 ▶). Dalton Trans. pp. 4149-4159; Kakaliou et al. (1999 ▶). Inorg. Chem. 38, 5964-5977]. There is a crystallographic mirror plane containing the Hf atom, one chloride ligand and the central diketiminate C atom. The Hf(IV) ion has slightly distorted square-pyramidal geometry surrounded by two N atoms from the β-diketiminate ligand and by three Cl(-) anions. Coordination bond lengths are Hf-N = 2.181 (3) Å, and Hf-Cl = 2.3148 (15) and 2.3727 (12) Å.

In the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(14)H(8)N(2)O(4))·2H(2)O, each of the two unique Ag(+) ions is two-coordinated by two N atoms from two different 1,4-bis-[(imidazol-1-yl)meth-yl]benzene ligands in an almost linear fashion [N-Ag-N = 170.34 (10) and 160.25 (10)°]. The 4,4'-diazenediyldibenzoate anions do not coordinate to Ag. O-H⋯O hydrogen bonds stabilize the crystal structure.

In the title compound, [CuCl(C17H19Cl4N3)]ClO4, the Cu(II) ion adopts a distorted square-planar geometry defined by one chloride ligand and the three nitro-gen atoms from the bis-[(pyridin-2-yl)meth-yl](3,5,5,5-tetra-chloro-pent-yl)amine ligand. The perchlorate counter-ion is disordered over three sets of sites with refined occupancies 0.0634 (17), 0.221 (16) and 0.145 (7). In addition, the het...
