Crystals of the complexes [CdI2 · C6H12S3]2 (1) and [Hg(C6H12S3)2](HgI3)2 (2) were obtained by diffusion of 1,4,7-trithiacyclononane (9 S 3) in ethanol into aqueous solutions of cadmium iodide and mercuric iodide/potassium iodide, resp. Both compounds crystallize monoclinically,1: space group P21/n, Z = 4, a = 1207.1(5), b = 909.9(2), c = 1240.3(7) pm, β = 92.59(9)°; 2: P21/c, Z = 2, a = 804.7(6), b = 934.0(6), c = 2167.9(4) pm, β = 94.34(7)°. 1 is dimeric, consisting of two [CdI2 · 9S3] units, connected via iodine bridges. Crystals of 2 contain sandwich-like cations [Hg(9S3)2]2+ and [HgI3]- anions, forming chains via Hg ··· S and Hg ··· I bridges.

Carbapenem Resistant Enterobacteriaceae

Carbapenem-resistant Enterobacteriaceae continue to threaten human health worldwide with few effective treatment options. New Delhi metallo--lactamase (NDM) enzymes are a contributing element that drive resistance to many -lactam- and carbapenem-based antimicrobials. Many NDM inhibitors are known, yet none are clinically viable. In this study, we present and characterize a new class of NDM-1 inhibitors based on a pyridine-2,6-dithiocarboxylic acid metal complex scaffold. These complexes display varied and unique activity profiles against NDM-1 in kinetic assays and serve to increase the effectiveness of meropenem, an established antibacterial, in assays using clinical Enterobacteriaceae isolates.
