[N-(1-Aza-nidyl-2,2,2-trichloro-ethyl-idene)-2,2,2-trichloro-ethanimidamide]-copper(II)
Abstract:
The title compound, [Cu(C(4)H(2)Cl(6)N(3))(2)], was obtained by the reaction of CCl(3)CN with ammonia in presence of CuCl. The Cu(II) atom is located about an inversion centre. The mol-ecule consists of three planar units (one central square CuN(4) and two C(2)N(3) fragments), adopting a staircase-like structure. The six-membered metallocycles have a sofa conformation with the Cu atom out of the plane of the 1,3,5-triaza-penta-dienyl ligands by 0.246 (5) Å. The ipso-C atoms of the CCl(3) substituents are slightly out of the 1,3,5-triaza-penta-dienyl planes by 0.149 (6) and -0.106 (6) Å. The CCl(3) groups of each 1,3,5-triaza-penta-dienyl ligand are practically in the energetic-ally favourable mutually eclipsed conformation. In the crystal, the mol-ecules are packed in stacks along the a axis. The mol-ecules in the stacks are held together by two additional axial Cu⋯Cl inter-actions of 3.354 (2) Å. Taking the axial Cu⋯Cl inter-actions into account, the Cu(II) atom exhibits a distorted [4 + 2]-octa-hedral coordination environment. The stacks are bound to each other by weak inter-molecular attractive Cl⋯Cl [3.505 (2)-3.592 (3) Å] inter-actions.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
