Περίληψη:
A series of new compounds prepared from reactions of
pyridine-3,5-dicarboxylic acid (PDCH2), bipositive d-metal ions (Cd2+,
Zn2+, Co2+ and Cu2+) and various template molecules [1,3-propanediol
(pdH(2)), diethanolamine (deaH(3)), N-phenyldiethanolamine (phdeaH(2)),
triethanolamine (teoaH(3)), 2-hydroxymethylpyridine (2hmpH),
3-hydroxymethylpyridine (3hmpH), 3-hydroxypropylpyridine (3hppH), and
4-hydroxymethylpyridine (4hmpH)] are reported. Among them,
[[(CH3)(2)NH2](2)[Cd-2(PDC)(3)]](n).4nDMF.6nH(2)O, [1],
[Mn(PDC)(DMF)](n), [2],
[Mn-3(PDC)(2)(INA)(2)(DMF)(1.5)(H2O)(0.5)](n).nDMF.2nH(2)O, [3], and
[Zn(PDC)(NMP)](n).nH(2)O, [4], are 3D coordination polymers,
[Zn(PDC)(H2O)(DMF)](n), [5], [Zn(PDC)(3hmpH)](n.)nDMF.0.5nH(2)O,
[6], and [Co(PDC)(3hmpH)(2)](n).0.25nDMF, [8], have 2D polymeric
structures, while [Zn(PDC)(2hmpH)(2)](2).2DMF, [7], is a 0D
binuclear complex, and [Cu(PDC)(3hmpH)(2)](n).0.5nDMF1.5nH(2)O, [9],
is a chain polymer. Topological analysis reveals that some of the
compounds display unusual structural architectures and two of them, in
particular [1] and [3], present new topological types. The effect of
the use of amino alcohol/polyol templates on the formation of the new
compounds is also discussed in detail. The thermal stability of the
prepared complexes was also studied. This study represents the initial
systematic investigation on the use of a combination of polytopic
nitrogen and oxygen-donor ligands and amino- or pyridine-alcohol
templates for the synthesis of new MOFs.
