Streszczenie

The ZnII compounds [ZnCl2(PTA)2] (1) (PTA = 1,3,5-triaza-7-phosphaadamantane) and [PTA–Me]2[ZnI2X2] [X = Cl (2a), X = I (2b); PTA–Me = N-methyl-1,3,5-triaza-7-phosphaadamantane] have been prepared by treating ZnCl2 with PTA and [PTA–Me]I, respectively, in methanol at room temperature. They are soluble in polar solvents such as water and methanol, stable in air, and have been characterized by IR, 1H NMR, 31P{1H} NMR, and 13C{1H} NMR spectroscopy, ESI-MS, elemental and single-crystal X-ray diffraction structural analyses (for 1 and 2a). Compound 1 exhibits a nearly regular tetrahedral Zn coordination, with the PTA ligands displaying the uncommon N-coordination with a low 31P NMR coordination shift. The molecular structure of 2a bears one discrete tetrahedral [ZnI2Cl2]2– anion and two cage-like [PTA–Me]+ cations, one of them being located in a void. Compound 1 represents the first example of a Zn complex bearing PTA or any derived ligand with a cage-like PTA cor
