“…Furthermore, it has been shown that dpma is a potent bidentate ligand stabilizing mononuclear [3][4][5] and oligonuclear [6] complexes as well as coordination polymers [7]. In recent years, we have shown that the N-protonated dpmaH + cation is an excellent monodentate ligand.…”

Abstract:The structural chemistry of a series of dpmaH (dpmaH = (dimethylphosphoryl)methanaminium) salts has been investigated using constructor graph representations to visualize structural dependencies, covering the majority of known dpmaH salts. It is shown that the structurally related α-aminomethylphosphinic acid can be integrated in the systematology of the dpmaH salts. Those dpmaH salts with counter anions that are weak hydrogen bond acceptors (ClO 4´, SnCl 6 2´, IrCl 6 2´, I´) tend to form head-to-tail hydrogen bonded moieties purely consisting of dpmaH + cations as the primarily structural motif. In structures with weak to very weak hydrogen bonds between the dpmaH + cations and the counter anions, the anions fill the gaps in the structures. In salts with medium to strong hydrogen bond acceptor counter ions (Cl´, NO 3´, PdCl 4 2´) , the predominant structural motif is a double head-to-tail hydrogen bonded (dpmaH + ) 2 dimer. These dimeric units form further NH¨¨¨X hydrogen bonds to neighboring counter anions X, which results in one-dimensional and two-dimensional architectures.

By the reaction of (dimethylphosphoryl)methanamine (dpma) with one equivalent of zinc(II) chloride in a concentrated hydrochloric acid solution and subsequent slow evaporation of the solvent, the title compound (dpmaH)ZnCl3 was obtained in quantitative yield. The primary reaction product mainly consists of larger brick-shaped colorless and smaller cuboide colorless crystals. Long-time storage over several months of these crystals in the mother liquor yielded a third polymorph (P21/n; a = 9.6639(1); b = 10.0271(1); c = 11.2446(1) Å; β = 98.964(1)°) of this compound. Similar to the two other modifications, its crystal structure consists of a zwitterionic dpmaHZnCl3 complex containing the cationic dpmaH+ ligand, which coordinates the zinc atom through its oxygen atom. Hydrogen bonds connect neighboring zwitterionic complexes to a layered structure. The motif of a hydrogen bonded dimer, similar to that found in the chain structure of polymorph I, is also present, but in the title structure these dimers form hydrogen bonds in two dimensions.
