[Cu(N^N)(POP)]+ complexes (POP = bis(2-(diphenylphosphino)phenyl)ether) in which the N^N domain is a 2,2′:6′,2′′-terpyridine (tpy) ligand have been prepared and characterized; N^N = tpy, 5,5′′-dimethyl-2,2′:6′,2′′-terpyridine (1), 4′-(4-tolyl)-2,2′:6′,2′′-terpyridine (2), 4′-(4-npropoxyphenyl)-2,2′:6′,2′′-terpyridine (3) and 4′-(4-nbutoxyphenyl)-2,2′:6′,2′′-terpyridine (4). In solution, the tpy domain in each [Cu(N^N)(POP)][PF6]
[Cu(N ^ N)(POP)] +配合物(POP =双(2-(二苯基膦基)苯基)醚)的第一个例子,其中N ^ N结构域是2,2':6',2'已制备并表征了'-叔吡啶(tpy)配体;N ^ N = tpy,5,5''-二甲基-2,2':6',2''-吡啶(1),4'-(4-甲苯基)-2,2':6',2' ′-联吡啶(2),4′-(4-正丙氧基苯基)-2,2′:6′,2′′-联吡啶(3)和4′-(4-正丁氧基苯基)-2,2′:6 ′,2′′-联吡啶(4)。在溶液中,每个[Cu(N ^ N)(POP)] [PF 6 ]配合物中的tpy域是C 2对称的,与三齿配位或涉及双齿配体的低能动力学过程一致;对于[Cu(2)(POP)] [PF 6 ]和[Cu(4)(POP)] [PF 6 ]的1 H NMR光谱显示295和210 K之间的变化可忽略不计。[Cu(tpy)(给出了[POP)] [PF 6 ]和[Cu(4)(POP)]
