Electronic and electrochemical properties of grid-type metal ion complexes (Fe+2 and Co2+) with a pyridine-pyrimidine-pyridine based bis(hydrazone)
The synthesis of new grid-type complexes of Co2+ and Fe2+ based on a highly soluble double hydrazone framework is reported. The data obtained from 1H NMR, FT-IR, and elemental analysis indicate that the complexes adopted a grid-like structure. Electronic properties of the metallogrids were analyzed...

| description |
The synthesis of new grid-type complexes of Co2+ and Fe2+ based on a highly soluble double hydrazone framework is reported. The data obtained from 1H NMR, FT-IR, and elemental analysis indicate that the complexes adopted a grid-like structure. Electronic properties of the metallogrids were analyzed by UV-Vis spectroscopy in chloroform, methanol, and dichloromethane. Additionally, cyclic voltammetry and square wave voltammetry were carried out in N,N-dimethylformamide (DMF). These compounds exhibited two oxidation processes corresponding to the organic ligand and several reductions events, comprising the ligand and metal centers. Furthermore, the interplay between the metal nature and the ligand framework was also studied in detail. These results represent an advancement in the chemistry of metallogrids not only because of the few reports concerning to the electrochemical properties found in the literature, but also for the design of novel hydrazone ligands of high solubility and easy preparation. |

Los datos obtenidos de resonancia magnética nuclear (RMN 1H), espectroscopía infrarroja con transformada de Fourier (FT-IR) y análisis elemental indican que los complejos adoptaron una estructura de tipo rejilla. Las propiedades electrónicas de las metalo-rejillas fueron analizadas a través de espectroscopía UV-Vis en cloroformo, metanol y diclorometano. Adicionalmente, se realizaron medidas de voltamperometría cíclica y voltametría de onda cuadrada en DMF. Los complejos exhibieron dos procesos de oxidación atribuidos al ligando orgánico y a varios eventos reductivos que comprometían al ligando y a los centros metálicos, por tanto, la interacción entre la naturaleza del ion metálico y la estructura del ligando fue analizada en detalle. Estos resultados representan un avance en la química de metalo-rejillas no solo por los escasos reportes de propiedades electroquímicas encontrados en la literatura, sino también por el diseño de nuevos ligandos hidrazónicos de alta solubilidad y fácil preparación.Neste trabalho relata-se a síntese de novos complexos de Co2+ e Fe2+ tipo grelha baseados na estrutura de uma hidrazona dupla altamente solúvel em solventes orgânicos. Os dados obtidos de ressonância magnética nuclear (1H RMN), espectroscopia de infravermelho com transformada de Fourier (FT-IR), e análise elementar indicam que os complexos adotaram a estrutura tipo grelha. As propriedades eletrônicas das grelhas metálicas foram analisadas por espectroscopia UV-Vis em clorofórmio, metanol e diclorometano. Adicionalmente, foram realizadas medidas de voltametria cíclica e voltametria de onda quadrada em DMF. Os compostos estudados exibiram dois processos de oxidação correspondentes ao ligando orgânico, e a vários eventos redutivos que envolvem o ligando orgânico e os centros metálicos. Além disso, a interação entre a natureza do metal e a estrutura do ligando foi estudada em detalhe. Estes resultados representam um avanço na química de metalo-grelhas não somente pelos escassos relatos de propriedades eletroquímicas encontrados na literatura, mas também pelo design de novos ligandos hidrazônicos de alta solubilidade e fácil preparação.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Químicahttps://revistas.unal.edu.co/index.php/rcolquim/article/view/66081Universidad Nacional de Colombia Revistas electrónicas UN Revista Colombiana de QuímicaRevista Colombiana de QuímicaChaur Valencia, Manuel Noé and Zuluaga Corrales, Héctor Fabio and Martínez, Gabriel (2018) Electronic and electrochemical properties of grid-type metal ion complexes (Fe+2 and Co2+) with a pyridine-pyrimidine-pyridine based bis(hydrazone).
