[N-(1-Azanidyl-2,2,2-trichloroethylidene)-2,2,2-trichloroethanimidamide]copper(II)

Abstract

The title compound, [Cu(C4H2Cl6N3)2], was obtained by the reaction of CCl3CN with ammonia in presence of CuCl. The CuII atom is located about an inversion centre. The mol­ecule consists of three planar units (one central square CuN4 and two C2N3 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-triaza­penta­dienyl ligands by 0.246 (5) Å. The ipso-C atoms of the CCl3 substituents are slightly out of the 1,3,5-triaza­penta­dienyl planes by 0.149 (6) and −0.106 (6) Å. The CCl3 groups of each 1,3,5-triaza­penta­dienyl ligand are practically in the energetic­ally favourable mutually eclipsed conformation. In the crystal, the mol­ecules are packed in stacks along the a axis. The mol­ecules in the stacks are held together by two additional axial Cu⋯Cl inter­actions of 3.354 (2) Å. Taking the axial Cu⋯Cl inter­actions into account, the CuII atom exhibits a distorted [4 + 2]-octa­hedral coordination environment. The stacks are bound to each other by weak inter­molecular attractive Cl⋯Cl [3.505 (2)–3.592 (3) Å] inter­actions.

Spodium, halogen and hydrogen bonds in the reactivity of bis(2,4-bis(trichloromethyl)-1,3,5-triazapentadienato)-Zn(ii)

“…2 Not only ligands, but the metal itself can also dictate the coordination geometry. For example, the coordination geometry in the bis(2,4-bis(trichloromethyl)-1,3,5-triazapentadienato) complexes [M{NHC(CCl 3 )NC(CCl 3 )NH} 2 ] (M = Cu ( 1 ), 3 Zn ( 2 ) 4 ) is square planar and trigonal pyramidal, respectively (Fig. 1).…”
