• Abstract

Single crystals of a novel compound, bis(ethyltriphenylphosphonium) tetrabromomanganate(II) dihydrate (BTP-Mn) were grown by solution growth-slow evaporation technique from aqueous solution of the compound at ambient temperature. The grown crystals were characterized by elemental analysis, powder X-ray diffraction, thermal analysis, nuclear magnetic resonance spectroscopy (NMR) and Fourier transform infra-red spectroscopy (FTIR) techniques. The chemical composition of the compound was revealed by elemental analysis and its crystallinity was conﬁrmed by powder X-ray diffraction. Thermal analysis conﬁrmed that the compound was stable up to 125°C. The various kinds of protons and carbons present in the compound were conﬁrmed by 1H NMR and 13C NMR technique respectively and the presence of phosphorous was conﬁrmed by ${}^{31}$P NMR spectrum in the compound. The modes of vibration of different molecular groups present in the compound were identiﬁed by FTIR spectral analysis. The second harmonic generation behaviour was tested by Nd:YAG laser source.
