                                The hydrothermal reactions of M(II) salts with 2,2':4',4":2",2"'-quaterpyridyl, 6,6"-di-2-pyridine (bisterpy) in the presence of a variety of anionic subunits have been investigated. The compounds [Cu-2(bisterpy)(H2O)(2)Cl-2]Cl-2 (1), [Cu-2(bisterpy)Br-4] (2), and [Cu-2(bisterpy) (NO3)(4)] . 2H(2)O (3 . 2H(2)O) are molecular. In contrast, [Cu-2(bisterpy)Cl-2(PF6)] (4), [Mn-2(bisterpy)(SO4)(2)] (5), [Zn-2(bisterpy)(SO4)(2)] (6), [Cu-2(phbisterpy)(SO4)(2)] . 2H(2)O (7 . 2H(2)O), [Cu-2(bisterpy)(MoO4)(2)] (8), [Zn-2(bisterpy)(MoO4)(2)] (9) [Cu-2(bisterpy)(H2O)(2)(SO4)] [Mo4O13] . 1.25H(2)O (10 . 1.25H(2)O) and [Cu-2(bisterpy)Mo8O26] . 2H(2)O (11-2H(2)O) are one-dimensional materials. The structural evolution of the molybdate series 8, 10, and 11 illustrates the profound influence of hydrothermal reaction conditions on product identity and architecture. The (PF6)(-) bridged solid 4 is mixed valence Cu(I)/Cu(II), a feature consistent with the magnetic properties of this material. (C) 2003 Elsevier B.V. All rights reserved.
