Abstract

Many reports describe the influence of additives or impurities on the physicochemical properties of crystals. On having obtainedtrans-RuCl2(C5H5N)(4)] as brown, needle-shaped crystals contrary to red or orange-red blocks reported previously, we herein revisit its study. This complex was obtained from the filtrate of an ensuing reaction mixture of RuCl3 center dot 3H(2)O, bis(2-hydroxy-l-naphthaldehyde)adipoyldihydrazone (npahH(4)) and pyridine in methanol. Findings from X-ray crystallographic data and spectra of IR, UV-Visible,H-1 and(13)C NMR along with other analytical studies of the complex are presented here. A comparative study with previously reported crystal forms was performed to understand the accompanying molecular structural differences in the physical (shape, size and color) morphological alteration. Further probing into molecular dynamics, the molecular interactions were analyzed and quantified using computational methods. The symmetry of intermolecular interaction in C-HMIDLINE HORIZONTAL ELLIPSISCl is different from earlier reported crystal forms. The intercontact HMIDLINE HORIZONTAL ELLIPSISH showed a major contribution (62.9%) for Hirshfeld surfaces. Also, we report antibacterial activity of the complex against methicillin-resistantStaphylococcus aureusfollowed by thein silicodocking study that revealed its interaction with the residue Glu58 of ATPase subunit ofS. aureusGyrB. Additional studies on its toxicity using rat models revealed this complex as non-toxic to animals.
