CH(2)Cl(2)), in the order H < mesityl < 2-pyridyl < 4-tolyl < 4-biphenylyl < 2-thienyl < 4-(dimethylamino)phenyl (431 nm in CH(2)Cl(2)), which correlates with the decreasing order of oxidation potentials. A similar order is also observed in the emission maxima, ranging from 491 nm for [PtL(1)Cl] to 588 nm for the 4-(dimethylamino)phenyl-substituted complex. The emission spectra of all of the complexes, except
The reaction of 2-ethynylpyridine with [Co(η5-C5H5)(PPh3)2] in addition to the expected two isomeric cobaltacyclopentadienes, gives a new complex formulated as [Co(η5-C5H5)(NC5H4C2H)3]. An X-ray diffraction study proved this to be a cobaltacyclopentene complex which presumably results from a pyridyl group-assisted DielsAlder addition of 2-ethynylpyridine to the intermediate 2,4-pyridylcobaltacyclopentadiene
2-乙炔基吡啶与反应[CO(η 5 -C 5 H ^ 5)(PPH 3)2 ]在除了预期的两种异构体cobaltacyclopentadienes,给出一个新的复杂的配制为[CO(η 5 -C 5 H ^ 5) (NC 5 H 4 C 2 H)3 ]。X射线衍射研究证明这是钴环戊烯络合物,可能是由吡啶基辅助的DielsAlder将2-乙炔基吡啶添加到中间体2,4-吡啶基钴环戊二烯中,然后氢迁移引起的。

The metal complex comprises a multivalent carboxylic acid compound, at least one metal ion selected from ions of metals belonging to Groups 2 to 13 of the periodic table, an organic ligand capable of multidentate binding to the metal ion, and a C1 or C2 monocarboxylic acid compound. The metal complex has excellent gas adsorption, storage, and separation performance as well as excellent durability. The metal complex is stably present under high temperature and high humidity, and can maintain high adsorption performance.
Disclosed is a method for producing a metal complex comprising a multivalent carboxylic acid compound, at least one metal ion, an organic ligand capable of multidentate binding to the metal ion, and a monocarboxylic acid compound, wherein the metal ion is used in the form of a metal salt having a counter anion of the metal ion, a conjugate acid of the counter anion having a first dissociation exponent larger by 0 to 6 than that of the multivalent carboxylic acid compound, and at least one of the multivalent carboxylic acid compound, the metal ion, the organic ligand capable of multidentate binding, and the monocarboxylic acid compound is reacted in a suspended state. This method can effectively produce a metal complex.
