“…Similarly, manual grinding of the organometallic dicarboxylic acid complex [Fe(η 5 ‐C 5 H 4 COOH) 2 ] with a variety of solid bases, namely 1,4‐diazabicyclo[2.2.2]octane, 1,4‐phenylenediamine, piperazine, trans ‐1,4‐cyclohexanediamine and guanidinium carbonate, has been used to generate quantitatively the corresponding organic–organometallic cocrystals , . See Figure for the cocrystals with 1,4 cyclohexane diamine and piperazine.…”

The investigation of the factors responsible for the stability of the diverse crystal forms that a given molecule can adopt in the solid state (polymorphs, hydrates, cocrystals, etc.) requires an appreciation of the relationship between static and dynamic behavior of atoms and molecules about equilibrium and far from equilibrium positions in the crystal structure. This is particularly relevant when dealing with molecules that are structurally nonrigid at ambient conditions in other media (solution, gas phase). The ease of motion of molecules in molecular crystals depends on the distribution of first neighboring molecules and on the network of intermolecular interactions, which are, in turn, also responsible for the relative thermodynamic stability of solid phases. The knowledge of the intermolecular interactions and of their interplay with the ionic char- [a]

“…The corresponding complexes were generated quantitatively as pure compounds, as verified by powder X-ray diffraction (PXRD) and comparison with data obtained by single-crystal X-ray diffraction. 148 In a similar way, hybrid organic−organometallic materials 177 and 178 could be formed via a solid−solid reaction of 1,1′-dipyridyl-ferrocene 176 with various organic diacids (fumaric, succinic, tridecanedioic, terephthalic, trimesic, and thiophene-2,5-dicarboxylic acids). 149 When linear alkyl diacids such as adipic, suberic, azelaic, and sebacic acids were utilized, new supramolecular macrocyclic adducts were synthesized (Figure 4).…”

Organometallic complexes: these two words jump to the mind of the chemist and are directly associated with their utility in catalysis or as a pharmaceutical. Nevertheless, to be able to use them, it is necessary to synthesize them, and it is not always a small matter. Typically, synthesis is via solution chemistry, using a roundbottom flask and a magnetic or mechanical stirrer. This review takes stock of alternative technologies currently available in laboratories that facilitate the synthesis of such complexes. We highlight five such technologies: mechanochemistry, also known as solvent-free chemistry, uses a mortar and pestle or a ball mill; microwave activation can drastically reduce reaction times; ultrasonic activation promotes chemical reactions because of cavitation phenomena; photochemistry, which uses light radiation to initiate reactions; and continuous flow chemistry, which is increasingly used to simplify scaleup. While facilitating the synthesis of organometallic compounds, these enabling technologies also allow access to compounds that cannot be obtained in any other way. This shows how the paradigm is changing and evolving toward new technologies, without necessarily abandoning the round-bottom flask. A bright future is ahead of the organometallic chemist, thanks to these novel technologies. CONTENTS1. Introduction 7530 2. Technologies 7530 2.1. Grinding and Milling 7530 2.2.

“…Hence these diluents KBr, KCl, NaCl, CaCl 2 , NaNO 3 , BaSO 4 , CaCO 3 and Al 2 O 3 were screened for either good pellet formation or set out reactions with the complexes. It was observed that BaSO 4 , CaCO 3 and Al 2 O 3 could not form a good pellet for FT IR measurement of the complexes. A simple process of forming a good pellet for FT IR measurement could generate a reaction because of high amount of energy involved.…”
