Los MOFs (Metal-Organic Frameworks), son una nueva clase de materiales híbridos microporosos definidos como redes extendidas, conformados por iones metálicos unidos mediante enlaces covalentes coordinados con ligandos orgánicos polifuncionales, formando estructuras en 1D, 2D y 3D. Este estudio computacional evalúa las propiedades electrónicas y reactividad química de una sección de la red metal-orgánico (MOFs) para el cobre con ligandos carboxilato (benzoato) reportado en la Cambridge Structural Database (CSD) denominado clúster de cobre hexaquis (m2-Benzoato-O,O')-hexacobre(I), con el fin de explicar el comportamiento de los sitios activos presentes en su estructura. El cálculo se realizó con el programa Q-Chem 4.0, el cual es utilizado para predicciones precisas de estructuras moleculares, reactividades y espectros vibratorios, electrónicos y de RMN, utilizando la interfaz gráfica de Spartan 14 versión 1.1.4 y el funcional de densidad hibrido B3LYP y la función base 6-31G*.

The dSNAP computer program has been used to classify searches of the Cambridge Structural Database for two ligands: —O—CH2—CH2—O— and N(CH2CH2O—)3 commonly found in metal-organic systems. The clustering method used is based on total geometries (i.e. all the lengths and angles involving all the atoms in the search fragment, whether bonded or not) and proved capable of distinguishing in a wholly automatic, objective way between different types of metal complex purely on the basis of the geometry of the ligand and the relative positions of the O atoms to the metals.

The Cambridge Structural Database (CSD) contains a complete record of all published organic and metal–organic small-molecule crystal structures. The database has been in operation for over 50 years and continues to be the primary means of sharing structural chemistry data and knowledge across disciplines. As well as structures that are made public to support scientific articles, it includes many structures published directly as CSD Communications. All structures are processed both computationally and by expert structural chemistry editors prior to entering the database. A key component of this processing is the reliable association of the chemical identity of the structure studied with the experimental data. This important step helps ensure that data is widely discoverable and readily reusable. Content is further enriched through selective inclusion of additional experimental data. Entries are available to anyone through free CSD community web services. Linking services developed and maintained by the CCDC, combined with the use of standard identifiers, facilitate discovery from other resources. Data can also be accessed through CCDC and third party software applications and through an application programming interface.

The Cambridge Structural Database (CSD) is the largest repository of crystal structures of organic and metal–organic compounds, containing over 1.1 million entries. Over 3300 of the deposits are structures determined under high pressure, with the number being strongly affected by the experimental requirements of the high-pressure techniques. Nevertheless, it still presents a population sufficiently representative for statistical data mining. In this work, an in-depth analysis of this population is presented, showing where contributors of high-pressure depositions come from, which journals high-pressure structures are published in, and also providing information on some trends in high-pressure crystallography and how they have changed over the years elucidated from data collected in the CSD. The ultimate goal of this article is to bring the high-pressure crystallography content in the CSD to a wider audience of scientists.

We successfully demonstrate that the chemical bath deposition (CBD) method is a versatile method for synthesizing phase-pure and uniform MOFs by controlling their nucleation stages and pore structures.
