“…The cobalt PCPs were synthesized by following a procedure analogous to the literature [52,53] . In a typical experiment, Co(NO 3 ) 2 .6H 2 O (82.20 mg, 0.28 mmol) was dissolved in 5 mL of anhydrous DMF, and then DBTA (0.42 mmol) solution in anhydrous DMF (5 mL) was added dropwise.…”

After stirring for 15 min, the solution was transferred to a teflon-lined stainless-steel autoclave and incubated at 160 °C for 24 h. Then, the reaction was cooled down to room temperature, and the powder was separated by centrifugation, washed with DMF and water several times, and dried in a vacuum oven at 60 °C for 12 h (Yield = 30.6 %).…”

Abstract2,2’‐Bipyridine‐derived two chelating linkers containing two and three bipyridine units were synthesized and characterized. Solvothermal condensation of these linkers with Co(NO3)2.6H2O generated cobalt‐based porous coordination polymers (Co‐PCPs). The scanning electron microscopy studies revealed the macroporous nature of the Co‐PCPs, with the highest surface area achieved up to 441.1 m2 g−1. The Co‐PCPs were found to be effective catalysts in the degradation of the anionic dyes, methyl orange (MO) and orange 2 (OII), in the presence of sodium borohydride. Also, the synthesized PCPs were found to selectively catalyse the degradation of anionic dyes from a mixture of dyes (~99 % degradation in 55 min). Regeneration studies showed that the PCPs could be regenerated and reused for more than five cycles with ~98 % retention of degradation efficiency and are promising materials for the selective degradation of anionic dyes from wastewater.

Two complexes [MnL 2 (H 2 O) 2 ]·2ClO 4 (complex 1) and [CuL(H 2 O) 3 ]·2NO 3 (complex 2) (where L = 3,5-bis(1-imidazoly) pyridine) were designed and synthesized. The structures of the complexes were characterized by X-ray crystallography, elemental analyses, and infrared spectrum. The interaction capacity of the complexes with calf thymus DNA has been investigated by UV and fluorescence spectroscopy. Gel electrophoresis assay demonstrated the ability of the complexes to cleave the pBR322 plasmid DNA. Efficient binding properties of DNA were established by UV-vis, fluorescence, and gel electrophoresis. The intrinsic binding constants (K b ) were calculated to be 0.1524, 0.1041 for complexes 1-2, respectively. The cytotoxic activity of the two complexes exhibited a higher cytotoxicity against HeLa cell lines and lower cytotoxicity toward the normal cell lines. Flow cytometry demonstrated the cancer cell inhibitory rate of two complexes. Furthermore, computer-aided molecular docking studies were performed to visualize the binding mode of the drug candidate at the molecular level. Interestingly, complex 1 exhibited a significant cancer cell inhibitory rate than cisplatin and other complexes.

Monomeric [Co(II)(hep-H)(H2O)4]SO4 [1]SO4 and [Co(II)(hep-H)2(H2O)2](NO3)2 [2](NO3)2 have been developed from 2-(2-hydroxyethyl)pyridine (hep-H) and CoSO4·7H2O/Co(NO3)2·6H2O, respectively, at 298 K. On exposure to heat (120 °C), the light orange single crystal of [1]SO4 transforms to a pink single crystal corresponding to the neutral sulfato bridged dimeric complex [(Co(II)(hep-H)(H2O)2(μ2-sulfato-O,O'))2](3). However, the orange single crystal of [2](NO3)2 transforms to the single crystal of monomeric [Co(II)(hep-H)2(NO3)]NO3 [4]NO3 (orange) upon exposure to heat (110 °C) where one of the NO3(-) counter anions in [2](NO3)2 moves to the coordination sphere. The facile SCSC transformations of [1]SO4 (orange) → 3 (pink) and [2](NO3)2 (orange) → [4]NO3 (orange) involve intricate multiple bond breaking and bond forming processes without losing the crystallinity. Moreover, the immersion of the pink single crystal of 3 in 1 N HCl results in a green single crystal of ionic monomeric [Co(II)(H2O)6]·SO4[5]SO4, which indeed demonstrates the unprecedented unique two-step SCSC transformations.
