Abstract

NaCd(H 2 PO 3 ) 3 ·H 2 O was synthesized in solution and its structure was studied by single-crystal X-ray diffraction. It crystallizes in the orthorhombic system (Pbca, Z = 8) with the cell parameters: a = 9.290(2) Å, b = 15.1236 (23)

Synthesis, Structural Characterization, and Biological Activities of Organically Templated Cobalt Phosphite (C4N2H14)[Co(H2PO3)4]·2H2O

“…The band appearing at 2450 cm −1 corresponds to the stretching vibration of P-H bond which is the characteristic bond of phosphite groups, whereas the bands from 990 to 1030 cm −1 are assigned to the bending mode of P-H. The vibration modes centered at 570, 1050, and 1160 cm −1 are ascribed to the stretching vibration of PO 3 group, while the one located at 910 cm −1 presents the stretching vibration of P-OH [20]. The set of bands related to the stretching vibration and deformation of the OH group belonging to water molecules is observed at around 3000 and 1640 cm −1 [32,33].…”

“…Within this class of structures, hybrid phosphite continues to attract intense research attention from all facets of material scientists since it promoted the formation of a new range of structures with various architectures and dimensionality [8]. These materials might exhibit different types: simple (single metal) [9][10][11][12], mixed-metal [13][14][15][16][17][18][19][20] or hybrid (organic-inorganic) [5,21]. In this context, we have described in the present paper the synthesis, crystal structure, spectroscopic characterization via Fourier transform infrared (FTIR) analysis, and thermal behavior of the new hybrid phosphite (C 4 N 2 H 14 )[Co(H 2 PO 3 ) 4 ]·2H 2 O.…”
