“…The asymmetric unit contains two molecules of 9 which are so similar that only one of them is discussed and displayed in Figure . Similar to the coordination compounds [ZnCl 2 (tmeda)] and [ZnCl 2 (tmcda)], the zinc center displays a pseudotetrahedral environment with a small N1–Zn1–N2 angle [87.95(7)°] and a large Cl1–Zn1–Cl2 angle [120.18(3)°]. The coordinating bond lengths are quite similar to 2.086(2) Å (N1–Zn1) and 2.076(2) Å (N2–Zn1).…”

The coordination of (R,R)-tetramethylcyclohexane-1,2-diamine derivatives with stereogenic nitrogen centers to zinc and mercury halides is investigated. It is shown that the resulting complexes display one specific configuration at the stereogenic nitrogen centers. This fact is unusual due to the fast inversion of nitrogen centers but highly desirable as the stereoinformation of the ligands is brought closer to the metal centers of the potential catalysts. A combination of NMR studies and quantum chemical calculations gives insight into the selective formation of one specific configuration at the stereogenic nitrogen centers of the zinc complexes.

“…The bond lengths (Table 2) related to the Zn atom are comparable with those observed in similar zinc complexes with tetrahedral geometries. [21][22][23] The bond angles related to the Zn atom range from 85.4(2) to 120.4 (2) , indicating the distortion of the tetrahedral coordination.…”

A mononuclear zinc(II) complex, [ZnClL(N 3 )], where L is 1,2-diaminocyclohexane, was synthesized and characterized by elemental analysis, IR spectrum, and single-crystal X-ray diffraction. The crystal of the complex crystallizes in the monoclinic space group P2 1 /m, with unit cell dimensions a D 6.146 (2) A , b D 7.042(2) A , c D 12.498(3) A , b D 99.782(3) , V D 533.1(2) A 3 , Z D 2, R 1 D 0.0517, wR 2 D 0.1470. The Zn atom of the complex is in a tetrahedral coordination, with two N atoms of the ligand L, one azide N atom, and one Cl atom. The complex has moderate level of resistance against cell lines HeLa, Hep-G2, KB, and AGZY-83a.
