“…As shown in Figure 1, there is one crystallographically distinct Co located at special position (½ 0 ½) (Table 1). The asymmetric unit of (H2DAB)[Co(H2PO3)4]•2H2O, which contains 13 non-hydrogen atoms located on general positions (Table 1), including 1 water oxygen named O (13). Cobalt cation shows octahedral geometry, coordinating six oxygen atoms from adjacent phosphite groups.…”

“…Within this class of structures, hybrid phosphite remains as an important focus of many material scientists due to the wide, and sometimes novel, range of structures exhibiting various architectures and dimensionality [8]. Such resulting martials can either be simple (single metal) [9][10][11][12], mixedmetal [13][14][15][16][17][18][19][20] or hybrid (organic-inorganic) [21,22]. In this context, we describe in the present manuscript the synthesis, crystal structure, spectroscopic characterization via Fourier transform infrared (FTIR) analysis, and thermal behavior of the new hybrid phosphite (H2DAB)[Co(H2PO3)4]•2H2O.…”

A novel hybrid cobalt phosphite, (H2DAB)[Co(H2PO3)4]·2H2O, has been synthesized by using slow evaporation method, in the presence of cobalt nitrate, phosphorous acid and 1,4- dia-minobutane (DAB= 1,4- diaminobutane) as a structure-directing agent. Single crystal X-ray diffraction analysis showed that the compound crystallizes in the P-1(n.2) triclinic space group, with the following unit cell parameters (Å, °) a = 5.4814 (3), b = 7.5515 (4), c = 10.8548 (6), α = 88.001 (4), β = 88.707 (5), γ = 85.126 (5), and V= 447.33 (4) Å3. The crystal structure was built up from cor-ner-sharing [CoO6] octahedra, forming chains parallel to [001], which are interconnected by H2PO3 pseudo-tetrahedral units. The deprotonated cations, residing between the parallel chains, interacted with the inorganic moiety via hydrogen bonds leading thus to the formation of the 3D crystal structure. The Fourier transform infrared spectrum showed characteristic bands corresponding to the phosphite group and the organic amine. The thermal behavior of the compound consisted mainly of the loss of its organic moiety and the water molecules. The biological tests exhibited significant activity against Candida albicans and Escherichia coli strains in all used concentrations, while less inhibitory activity was pronounced against Staphylococcus epidermidis and Saccharomyces cerevisiae, and in the case of multi-cellular organisms, no activity against the nematode model Steinernema feltiae was detected.

“…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.…”

A novel hybrid phosphite (C4N2H14)[Co(H2PO3)4]·2H2O was synthesized with 1,4- diaminobutane (dabn) as a structure-directing agent using slow evaporation method. Single crystal X-ray diffraction analysis showed that it crystallizes in the P\-1 triclinic space group, with the following unit cell parameters (Å, °) a = 5.4814 (3), b = 7.5515 (4), c = 10.8548 (6), α = 88.001 (4), β = 88.707 (5), γ = 85.126 (5), and V = 447.33 (4) Å3. The crystal structure was built up from corner-sharing [CoO6]-octahedrons, forming chains parallel to [001], which are interconnected by H2PO3− pseudo-tetrahedral units. The diprotonated 1,4-butanediammonium molecules, residing between the parallel chains, interacted with the inorganic moiety via hydrogen bonds leading thus to the formation of the 3D crystal structure. The Fourier transform infrared spectrum showed characteristic bands corresponding to the phosphite group and the organic molecule. The thermal decomposition of the compound consisted mainly of the loss of the organic moiety and the water molecules. The biological tests exhibited significant activity against Candida albicans and Escherichia coli strains in all used concentrations, while less activity was pronounced when tested against Staphylococcus epidermidis and Saccharomyces cerevisiae, while there was no activity against the nematode model Steinernema feltiae.

The crystal structure was built up from corner-sharing [CoO6]-octahedrons, forming chains parallel to [001], which are interconnected by H2PO3 pseudo-pyramid units. The diprotonated 1,4-diaminobutane molecules, residing between the parallel chains, interacted with the inorganic moiety via hydrogen bonds leading thus to the formation of the 3D crystal structure.
