Solid state coordination chemistry: structural consequences of variations in tether length in the oxovanadium–copper–bisterpy–{O3P(CH2)nPO3}4− system, n = 1–6 (bisterpy = 2,2′:4′,4″:2″,2‴-quarterpyridyl-6′,6″-di-2-pyridine)

Abstract

Hydrothermal reactions of Na3VO4, an appropriate Cu(II) source, bisterpy and an organodiphosphonate, H2O3P(CH2)nPO3H2 (n = 1–6) yielded a family of materials of the type {Cu2(bisterpy)}4+/VxOyn/{O3P(CH2)nPO3}4−. This family of bimetallic oxides is characterized by an unusual structural diversity. The oxides [{Cu2(bisterpy)}V2O4{O3PCH2PO3H}2] (1), [{Cu2(bisterpy)(H2O)}VO2{O3P(CH2)3PO3}{HO3P(CH2)3PO3H2}] (4) and [{Cu2(bisterpy)}V2O4{O3P(CH2)6PO3H}2]·2H2O (7·2H2O) are one-dimensional, while [{Cu2(bisterpy)(H2O)2}V2O4{O3P(CH2)2PO3}{HO3P(CH2)2PO3H}2] (2), [{Cu2(bisterpy)}V4O8{O3P(CH2)3PO3}2]·4H2O (3·4H2O) and [{Cu2(bisterpy)}V2O4(OH)2{O3P(CH2)4PO3}]·4H2O (5·4H2O) are two-dimensional. The V(IV) oxide [{Cu2(bisterpy)}V4O4{O3P(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.
