Abstract
The title phosphonate-based organic-inorganic hybrid framework, poly[bis(dimethylammonium) [(μ4-2,5-dihydroxybenzene-1,4-diphosphonato)zinc(II)]], {(C2H8N)2[Zn(C6H4O8P2)]} n , was formed unexpectedly when dimethylammonium cations were formed from the in situ decarbonylation of the N,N-dimethylformamide solvent. The framework is built up from ZnO4 tetrahedra and bridging diphosphonate tetra-anions to generate a three-dimensional network comprising [100] channels occupied by the (CH3)2NH2 + cations. Within the channels, an array of N - H⋯O hydrogen bonds help to establish the structure. In addition, intramolecular O - H⋯O hydrogen bonds between the appended -OH groups of the phenyl ring and adjacent PO3 2- groups are observed.
