“…If the effect of the additional ligand or ligands increases the stability of the formed crystal structure, the storage volume and some other properties, this is a positive situation for newly obtained compounds. In a previous study, some new Hofmann-type compounds and Hofmann-type-like clathrates were obtained in powder and crystal form by using water molecules (H2O), K2Ni (CN)4 compound and zinc (Zn) transition metal atoms [16,18,19]. Therefore, this compound is currently a first in its field.…”

In this study; a new heterometallic compound defined by the open formula [Cd(H2O)2Ni(CN)4]4[Cd(H2O)4Ni(CN)4]5 was synthesized in crystal form. Consisting of components such as water molecules, [Ni(CN)4]2− anions, and cadmium transition metal atoms, this new crystal structure has no analogues which might have been previously obtained, even with other transition metal atoms. It is a new compound and a unique example of a crystal. The structural properties of this heterometallic compound have been characterized by single crystal X-ray diffraction spectroscopy (SC-XRD), FT-IR spectroscopy, thermal analysis and elemental analysis methods. According to the data obtained from the SC-XRD technique, this heterometallic compound has a monoclinic crystal system and a C2/c space group. The asymmetric unit of this compound consists of five Cd(II) ions, five Ni(II) ions, eighteen cyanide ligands, and fourteen coordinated water ligand molecules. In addition, theoretical calculations have been made with the Gaussian 03 program in order to obtain more information about this heterometallic Hofmann-type-like compound. The chemical properties of this new compound have been calculated using its HOMO and LUMO values and the natural bond orbital (NBO) analyses. In addition, Hirshfeld surface analysis of the asymmetric unit of this compound has been performed with the CrystalExplorer program. As a result of the Hirshfeld surface analysis, extensive information has been obtained about the weak intramolecular and intermolecular forces that form this new crystalline compound.

Present work describes the synthesis and characterization of complexes of 4-[(2E)-2-benzylidenehydrazinyl]-7H-pyrrolo[2,3-d]pyrimidine with Fe(II), Mn(II), Co(II), Ni(II), Pd(II), Zn(II), Cu(II), Cd(II) and Hg(II). The results of the elemental and spectroscopic analyses suggest a 1:2 metal-ligand ratio, [ML2]. The electronic spectra and magnetic moments of the metal(II) complexes suggest that Fe(II), Mn(II), Co(II) and Ni(II) complexes are in an octahedral geometry, while Pd(II) in a square planar ligand geometry. In contrast, the Cu(II), Zn(II), Cd(II) and Hg(II) are in tetrahedral geometry. The conductance measurements in nitrobenzene suggest the non-electrolytic nature of all the metal-coordination compounds. The tested biological species viz. Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus cereus, Proteus mirabilis, Klebsiella oxytoca, Aspergillus niger, A. flavus and Rhizopus stolonifer exhibited the moderate to strong antimicrobial activity. At 10 mg/mL concentration in nitrobenzene, cobalt(II) complex is observed to be a more promising antimicrobial than any other metal(II) complexes synthesized. The antioxidant potential of the synthesized metal(II) compounds was also evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and shows the high DPPH radical scavenging activity. The nickel complex had the highest DPPH radical scavenging activity compared to the other metal(II) complexes.
