“…The most common is the N-N-chelation coordination mode favored by the anti-(E,E) form [6,13,14], but the coordination of these ligands via oxygen atoms from oximic groups is also known [15,16]. vic-Dioximes can form coordination compounds in molecular [17,18], monodeprotonated [19][20][21][22] and bisdeprotonated [23] forms. In the coordinated state the intramolecular hydrogen bonds between the oxime anions can be replaced with boron compounds (BF2 + , BF 2+ , B(C6H5)2 + , B(OH)2 + ), thus encapsulating the respective compounds [24][25][26][27].…”

The vic-dioximes are compounds with various industrial uses and scientific applications. Many coordination compounds have been synthesized based on vicdioximes. This study presents the synthesis and full characterization of two vicdioximes based on dichloroglyoxime, p-aminobenzoic acid and p-aminotoluene. Their structures were proved by IR, 1 H, 13 C and 15 N NMR spectral analysis and single crystal X-ray diffraction. One of the reported vic-dioximes, bis(di-p-aminotoluene)glyoxime mono-p-aminotoluene trihydrate showed good to moderate antimicrobial activity against both non-pathogenic Gram-positive and Gram-negative bacteria (Bacillus subtilis and Pseudomonas fluorescens), phytopathogenic (Xanthomonas campestris, 2 Erwinia amylovora, E. carotovora) and the fungi (Candida utilis and Saccharomyces cerevisiae) at MIC -70-150 μg/mL.

Two different phase-pure cobalt(II) cyanoguanidine bromide coordination compounds, Co(C2N4H4)2(H2O)4·2Br·2H2O (1) and Co3(C2N4H4)8(H2O)8·6Br (2), were precipitated from aqueous and methanol solutions, respectively, and their structures were solved and refined from X-ray single-crystal data at 100 K. Both 1 and 2 crystallize in the triclinic system with space group P. The structure of 1 consists of two crystallographically distinct isolated CoO4N2 octahedral units plus bromide anions and crystal water molecules, whereas 2 is built from both isolated octahedra and discrete binuclear cluster units made from edge-sharing octahedra. Diffuse reflectance spectra and IR analysis then go on to highlight optical and vibrational differences between these two compounds. The magnetic susceptibility of 1 is consistent with either isolated or very weakly interacting Co2+ centers whereas the magnetic susceptibility of 2 evidences the potential weak antiferromagnetic exchange interactions that may arise from superexchange within the binuclear clusters.
