| Abstract |
The structure of the title compound, [Cu(PTA)(4)]Cl center dot 6H(2)O (PTA is 1,3,5-triaza-7-phosphaadamantane, C6H12N3P), is composed of discrete monomeric [Cu(PTA)(4)](+) cations, chloride anions and uncoordinated water molecules. The Cu I atom exhibits tetrahedral coordination geometry, involving four symmetry-equivalent P-bound PTA ligands. The structure is extended to a regular three- dimensional supramolecular framework via numerous equivalent O-H center dot center dot center dot N hydrogen bonds between all solvent water molecules (six per cation) and all PTA N atoms, thus simultaneously bridging each [Cu(PTA)(4)](+) cation with 12 neighbouring units in multiple directions. The study also shows that PTA can be a convenient ligand in crystal engineering for the construction of supramolecular architectures. |
