Isoreticular Investigation into the Formation of Four New Zinc Alkylbisphosphonate Families
摘要:
Through the systematic investigation of zinc alkylbisphosphonates, four new structural families have been obtained. These families are named zinc alkyl-tunnel, -gate, -cation, and -sheet (ZAT, ZAG, ZAC, and ZAS) for convenience and have been synthesized and further extended through isoreticular design utilizing alkylbis(phosphonic acid) ligands of the formula H2O3PCnH2nPO3H2 (n = 3-6) (H(4)Ln). Both even- and odd-length chains were utilized to help determine the effect of chain conformation on structure formation. The investigation lead to two known compounds (ZAG-4, and ZAS-3) and nine new compounds, two of which contain large 1-D channels. The crystal structures of all compounds were determined by single-crystal X-ray diffraction. Of the nine new compounds, only seven of them fall into the new families. In three of the four families, the structure is controlled by alkyl-chain length and conformation (i.e., odd vs even), and in the fourth, a conformational distortion allows both odd and even lengths to form the given structure. Isoreticular species using n = 3 and 5 were obtained in both the ZAT and the ZAS families; using n = 4 and 6 were obtained in the ZAG family; and n = 4-6, in the ZAC family.

Hydrothermal reactions of Na3VO4, an appropriate Cu(II) source, bisterpy and an organodiphosphonate, H2O3P(CH2)nPO3H2
(n

The V(IV) oxide [Cu2(bisterpy)}V4O4O3P(CH2)5PO3H}4]·7.3H2O (6·7.3H2O) provides a relatively unusual example of a three-dimensional bimetallic oxide phosphonate. The structures reveal a variety of V/P/O substructures as building blocks.
