motif, leaving no scope for self-assembly with neutral ligand. Presented here is the self-association of anionic ligand 3-ureidobenzoic acid (2a) and neutral ligand 1-(3-(diphenylphosphanyl)phenyl)urea (1a) on a metal template to yield metal complex [COOC6H4NH(CO)NH2}Ph2PC6H4NH(CO)NH2}PdMeDMSO] (4a). The identity of 4a was established by NMR and mass spectroscopy. Along the same lines, 3-(3-phenylureido)benzoic
近年来,在金属上自组装两个中性配体以模仿二齿配体配位的自组装,但是金属模板上的阴离子配体与中性配体的自组装仍然是一个难以捉摸的目标。这种自组装受到另外的复杂性的阻碍,其中高度带负电的阴离子可以与超分子基序形成分子间氢键,而没有与中性配体自组装的范围。此处介绍的是金属模板上阴离子配体3-脲基苯甲酸(2a)和中性配体1-(3-(二苯基膦基)苯基)脲(1a)的自缔合,以生成金属络合物[COOC 6 H 4 NH( CO)NH 2 } Ph 2PC 6 H 4 NH(CO)NH 2 } PdMeDMSO](4a)。通过NMR和质谱确定4a的身份。同样,3-(3-苯基脲基)苯甲酸(2b)和1-(3-(二苯基膦酰基)苯基)-3-苯基脲(1b)在金属模板上自组装以生成钯配合物[COOC 6 H 4 NH(CO)NHPh} Ph 2 PC 6 H 4 NH(CO)NHPh} PdMePy](5c)。5c的存在已通过Job
