Dicarboxylate anion-dependent assembly of Ni(II) coordination polymers with 4,4′-dipyridyl sulfide

Abstract

Four new coordination polymers, [Ni(isop)(bps)(H2O)]2n·5H2O (1), [Ni(O2N–BDC)(bps)(H2O)]2n (2), [Ni(OH–BDC)(bps)2(H2O)]n (3) and {[Ni2(H2O)(tbip)2(bps)2]}n (4) (bps = 4,4′-dipyridyl sulfide, H2isop= isophthalic acid, O2N–BDC = 5-nitroisophthalic acid, OH–BDC = 5-hydroxyisophthalic acid, H2tbip = 5-tert-butyl isophthalic acid), have been isolated from parallel hydrothermal reactions of Ni(OAc)2·4H2O and bps with isop, O2N–BDC, OH–BDC and H2tbip, respectively.
