The following twelve mercurous and mercuric organophosphomates, bis/diphosphonates and phenylarsonates have been isolated and structurally characterized by single crystal X-ray diffraction, {sup 13}C-and {sup 31}P NMR, infrared and Raman spectroscopic methods: Hg{sub 2}(HO{sub 3}PC{sub 6}H{sub 5}){sub 2}(1), Hg{sub 2}(HO{sub 3}P(C{sub 6}H{sub 4})PO{sub 3}H)(2), Hg{sub 2}(HO{sub 3}P(C{sub 6}H{sub 4}){sub 2}PO{sub 3}H)(3), Hg{sub 2}(HO{sub 3}P(CH{sub 2}){sub 4}PO{sub 3}H)(4), Hg{sub 2}(O{sub 3}PC{sub 6}H{sub 5})·H{sub 2}O(5), (Hg{sub 2}){sub 2}(O{sub 3}P(CH{sub 2}){sub 2}PO{sub 3})(6), (Hg{sub 2}){sub 2}(O{sub 3}P(CH{sub 2}){sub 3}PO{sub 3})(7), Hg(O{sub 3}PC{sub 6}H{sub 5})·H{sub 2}O(8), Hg(O{sub 3}PCH{sub 2}C{sub 6}H{sub 5})·H{sub 2}O(9), Hg(O{sub 3}AsC{sub 6}H{sub 5})·H{sub 2}O(10), Hg{sub 3}(O{sub 3}AsC{sub 6}H{sub 5}){sub 2}(HO{sub 3}AsC{sub 6}H{sub 5}){sub 2}(11) and (Hg{sub 2})Hg{sub 3}(O{sub 3}P(C{sub 6}H{sub 4})PO{sub 3}){sub 2}·2H{sub 2}O(12). Compounds 1–7 are the first examples of mercurous phosphonates and di/bisphosphonates. They contain Hg{sub 2}O{sub 6} units, which consist of Hg{sub 2}{sup 2+} cations with Hg-Hg bond of ~2.5 Å length. Phenylphosphonates 1 and 5 are layered compounds, whereas bis/diphosphonates 2, 3, 4, 6 and 7 have pillared-layered and three-dimensional structures. Compounds 8–11 are layered mercuric phosphonates and phenylarsonates. Compound 12 is a three-dimensional mixed-valent mercury phenylenebisphosphonate. - Graphical abstract: The first examples of mercurous organophosphonates and organodiphosphonates have layered, pillared-layered and three-dimensional structures.
