一系列单位和复位异羟肟酸被用于离散的(0D)和(1-和2-D)扩展的网络配位络合物的合成和结构和物理表征。后者的例子包括一维配位聚合物{[Zn(II)(L3H)(2)]2MeOH}(N)(5；L3H2=2-(甲氨基)苯基异羟肟酸)和二维扩展网络{[Cu(II)(L2H)(H2O)(NO3)]H2O}(N)(5；L2H2=4-氨基-2-(乙酰氧基)苯异羟肟酸)。12-MC-4金属冠醚[Cu(ii)(5)(L4H)(4)(MeOH)(2)(NO3)(2)]3H(2)O4MeOH(7)是第一个使用新型配体N-hydroxy-2-[(2-hydroxy-3-methoxybenzyl)amino]benzamide(L4H3)构建的金属配合物。变温磁化率研究证实了7中铜(II)中心之间强烈的反铁磁性交换。配位聚合物5在蓝光区域(类似于421-450 nm)显示出光致发光，发射从溶液到固体的基色位移(类似于15-30 nm)。
A family of mono- and ditopic hydroxamic acids has been employed in the synthesis and structural and physical characterisation of discrete (0D) and (1- and 2-D) extended network coordination complexes. Examples of the latter include the 1-D coordination polymer {[Zn(ii)(L3H)(2)]2MeOH}(n) (5; L3H2 = 2-(methylamino)phenylhydroxamic acid) and the 2-D extended network {[Cu(ii)(L2H)(H2O)(NO3)]H2O}(n) (5; L2H2 = 4-amino-2-(acetoxy)phenylhydroxamic acid). The 12-MC-4 metallacrown [Cu(ii)(5)(L4H)(4)(MeOH)(2)(NO3)(2)]3H(2)O4MeOH (7) represents the first metal complex constructed using the novel ligand N-hydroxy-2-[(2-hydroxy-3-methoxybenzyl)amino]benzamide (L4H3). Variable temperature magnetic susceptibility studies confirm strong antiferromagnetic exchange between the Cu(ii) centres in 7. Coordination polymer 5 shows photoluminescence in the blue region (lambda(PL) similar to 421-450 nm) with a bathochromic shift of the emission (similar to 15-30 nm) from solution to the solid state.
