“…Due to the insolubility of the complexes in most of the common solvents employed, we failed to crystallize the materials as single crystals, rather than polycrystalline powders. A possible future solution to our inability to grow single-crystals is the use of a very interesting reaction/crystallization apparatus recently reported [51,52]. Nevertheless, we believe that the structural 5 study reported in this study is highly reliable and supported from spectroscopic data.…”

“…In order to grow single-crystals, we used a special glassware that consists in a branched tube designed by us [31] for doing the reaction and crystallization in a single step (see reference [31] for a detailed explanation). The detailed synthesis of 1 is explained here.…”

Supramolecular Assemblies in Pb(II) Complexes with Hydrazido-Based Ligands

et al. 2019

Herein, we describe the synthesis and single crystal X-ray diffraction characterization of several Pb(II) complexes using Schiff base hydrazido-based ligands and different counterions (NO3−, I– and ClO4). In the three complexes reported in this work, the lead(II) metal exhibits a high coordination number (n > 8) and thus it is apparently not involved in tetrel bonding interactions. Moreover, the aromatic ligands participate in noncovalent interactions that play an important role in the formation of several supramolecular assemblies in the solid state of the three Pb(II) complexes. These assemblies have been analyzed by means of Hirshfeld surface analysis and DFT calculations.

“…HL (pyridine-2-carboxaldehyde isonicotinoyl hydrazone) was prepared according to a literature method [54,55]. A branched tube method [56,57] was used for the synthesis of 1 (Figure S1, in the supplementary materials). Hence, solid Cd(NO 3 ) 2 ·4H 2 O (0.154 g, 0.5 mmol) and HL (0.113 g, 0.5 mmol) were introduced into the principal arm of a branched tube, followed by a gentle addition of EtOH to fill the arm.…”

“…These procedures include: (a) a branched tube method with a heat gradient that resulted in a single crystalline form of 1 ( Figure S1), and (b) a sonochemical method that led to the formation of nanoparticles of 1. Both methods are based on a reaction of cadmium(II) nitrate with HL in ethanol (Scheme 1), wherein HL was used as a recognized organic building block for the generation of coordination polymers [54][55][56][57].…”

Nanospheres of a new coordination polymer {[Cd 2 (µ-HL)(µ-L)(NO 3 ) 3 (H 2 O)]·H 2 O} n (1) were easily prepared by a sonochemical method from cadmium(II) nitrate and HL (HL, pyridine-2-carboxaldehyde isonicotinoyl hydrazone) in ethanol. Single crystals of 1 were also obtained using a branched tube method. The crystal structure of 1 indicates that the µ-HL/µ-L − blocks act as linkers between the Cd(II) centers, assembling them into 1D tooth-shaped interdigitated chains, which are further interlinked into a complex 3D H-bonded network with a rare hms (3,5-conn) topology. Nanoparticles of 1 were characterized by elemental analysis, FT-IR spectroscopy, and powder X-ray diffraction (XPRD), while their spherical morphology was confirmed by transmission electron microscopy (TEM). Furthermore, in the presence of a surfactant, the thermolysis of sonochemically generated nanoparticles of 1 led to the formation of cadmium oxide nanospheres (cubic CdO) with an average diameter of 10 nm. This study extends the application of sonochemical synthetic methods for the generation of phase pure nanoparticles of coordination polymers and their thermolysis products. nanoscale materials, the development of versatile, facile, and inexpensive methods for the preparation of nanocrystalline materials still remains a challenging area of research.Among a variety of strategies applied for the generation of nanoparticles, the sonochemical synthesis is particularly attractive, given its simplicity, cost effectiveness, quick reaction times, excellent yields, and purity of products [18,19]. Hence, in the past decade, ultrasonic irradiation has been applied for the synthesis of nanoparticles for a wide range of compounds [18][19][20][21][22][23][24][25][26][27][28]. In particular, synthesis of group 12 semiconductor nanoparticles (e.g., CdO, CdS, ZnO, ZnS) is of major interest, due to their size-and shape-dependent electronic and optical properties, as well as potential applications in light-emitting devices and nonlinear optics [29][30][31]. Cadmium oxide (CdO) is also an important inorganic semiconductor with a large band gap [32].On the other hand, coordination polymers (CPs) assembled from metal nodes and multidentate organic linkers can be used as precursors for a desirable type of nanoparticles. Such parameters as the composition, size and morphology of metal oxide nanoparticles can be influenced by selecting an appropriate type of metal-organic precursor, and tuning the experimental conditions. Interestingly, nanoscale CPs can also be applied for the preparation of nanomaterials with controlled particle size and uniform morphologies, and eventually more desirable properties [33][34][35][36].Considering all these points, and following our interests in crystal engineering, design of novel coordination polymers and derived functional materials [37-44], we focused our attention on developing a sonochemical synthetic approach for the preparation of a new cadmium(II) coordination polymer as a precursor for nanospheres of CdO. Another objective o...
