Název v původním jazyce

Carboxylate Tolerance of the Redox-Active Platform [Ru(mu-tppz)Ru](n), where tppz=2,3,5,6-Tetrakis(2-pyridyl)pyrazine, in the Electron-Transfer Series [(L)CIRu(mu-tppz)RuCl(L)](n), n=2+, +, 0, -, 2-, with 2-Picolinato, Quinaldato, and 8-Quinolinecarboxylato Ligands (L-)

Popis výsledku v původním jazyce

The neutral title complexes [(L1-3)ClRuII(mu-tppz)(RuCl)-Cl-II(L1-3)] [tppz = 2,3,5,6-tetrakis(2-pyridyl)pyrazine with L-1 = 2-picolinate, L-2 = 2-quinolinecarboxylate (quinaldate) and with the hitherto little used L-3 = 8-quinolinecarboxylate] have beenstructurally characterized as approximately anti- (1 and 3) and syn-configured isomers (2) with L ligand N (1 and 3) or 0 atoms (2) trans to the pyrazine N atoms of tppz. In contrast to 1 and 2 with five-membered chelate rings, complex 3 (which is isomeric with 2) contains six-membered chelate rings. Each system 1-3 thus features a significantly different coordination situation, and all complexes exhibit a considerably distorted tppz bridge, including a twisted central pyrazine ring. In spite of this,double one-electron reduction of the bridge is always possible, as is evident from electron paramagnetic resonance (EPA) and UV/vis spectroelectrochemistry.
