摘要：Graphical abstractPictures of the growing crystals.Display OmittedAbstractWe report the structural, morphological and optical activities of a paramagnetic manganite (La0.33Ca0.67MnO3) synthesized at 900 °C. A simple method of formation of complex was employed. A complex was formed between a pre-prepared manganite dissolved in HCl and reacted with an organic ligand (ethyl 4-nitrobenzoate). The optical and antimicrobial properties of a complex were determined. The Ultraviolet-visible and Fourier-transform infra-red spectroscopy were used in monitoring optical activities of the resulting product. It was observed to absorb in the visible region (205 nm and 256 nm). The peaks observed from the infra-red spectra indicated that the reaction occurred at the nitroso end of the ethyl 4-nitrobenzoate. The bacterial inhibitory property of the LCMO-ethyl 4-nitrobenzoate was determined against Pseudomonas aeruginosa, Candida albican, Aspergillus niger and Staphylococcus auerus. It was observed to inhibit the growth of all the microbes with zone of inhibitions of 60 mm, 56 mm, 45 mm and 32 mm, for Pseudomonas aeruginosa, Candida albican, Aspergillus niger and Staphylococcus auerus, respectively.•The method used was simple and a complex was formed within 6 h without the use of complicated equipment.•The method requires no heat treatment and can be prepared at room temperature.•LCMO-ethyl 4-nitrobenzoate was biologically active againstPseudomonas aeruginosa,Candida albican,Aspergillus nigerandStaphylococcus aureus.
