Abstract
The hydrothermal synthesis and crystal structure of seven new supramolecular, heterocyclic adducts of copper organophosphonates are presented. Compounds 1-4, [CuX(D)2][C6H5P(O)(OH) 2] [C6H5P(O)2(OH)], where D = 1,10-phenanthroline (phen) and X = Cl (1), Br (2), I (3), and NCS (4), are ionic in nature and possess a monoclinic structure, with the copper(II)-halide bond lying along a two-fold crystallographic axis. The crystals exhibit an alternating, lamellar structure in which 1-D 'ribbons' of [CuX(phen) 2]+ cations are interleaved with 2-D 'sheets' of anionic [C6H5P(O)(OH)2][C6H 5P(O)2(OH)]- dimers. The ribbons are associated through π-π bonding of the heterocyclic rings, and the acid sheets..
