Synthesis, crystal structure and NLO property of a nonmetal pentaborate [C6H13N2][B5O6(OH)4]

Synthesis, XRD Studies and NLO Properties of [p-H2NC6H4CH2NH3][B5O6(OH)4]·1/2H2O and NLO Properties of Some Related Pentaborate(1−) Salts

“…These compounds [11][12][13] were re-synthesized and their SHG efficiencies were also determined. 4 ] [19] and obtained a SHG efficiency of 0.6. This value was lower than that reported (0.9) but nevertheless it was significantly higher than that of the other pentaborate(1-) salts that we describe above.…”

“…CHN analysis was carried out at OEA laboratories Ltd in Callington, Cornwall. With the exception of 1 (see below) samples used in the powder SHG measurements were all prepared by literature methods [11][12][13]19] and had characterization data consistent with published data. …”

“…The second-harmonic generation (SHG) properties of BBO (b-BaB 2 O 4 ) and LBO (LiB 3 O 5 ) are well-known [15] and the NLO properties of many borate crystals have now been investigated. Many of the structures investigated for SHG properties have been on metal containing borates [16] and relatively few have had non-metal cations as partners [17][18][19][20]. This manuscript describes the synthesis and characterization 1, including it solid-state structure, and an investigation into its thermal and NLO (SHG) properties.…”

Hydrothermal Syntheses, Crystal Structure and Thermal Behavior of [(CH3)2NH2]2[B5O6(OH)4]2·[HCON(CH3)2] and [NH3CH2CH2NH3]2[B14O20(OH)6]

“…(4) 26 and other organic base templated nonmetal borates. 4,10,14,18 It is well known that multipoint hydrogen bond interactions play an important role in the formation and stability of low-dimensional structures. In this compound, the [B 5 O 6 (OH) 4 ] -groups are held together through the O-H…O hydrogen bonds between the bridge-oxygen atoms and terminal OH groups, forming a three-dimensional supramolecular structure with channels along axes b and c ( Figure 5) located in the inorganic channel and interact with the polyborate framework both electrostatically and via hydrogen bonds of N-H…O.…”

[Cu(C12N2H8)2(C2H3O2)][B5O6(OH)4]·C4H9NO: First Borate with Three‐dimensional Supramolecular Framework Formed by Hydrogen Bonds and π···π Stacking Interactions

“…Borate materials have attracted a great deal of attention in the past decades due to their rich structural chemistry and potential applications in mineralogy and industry, [1][2][3][4][5] especially applications based on their optical properties such as nonlinear optics [6][7][8][9][10] and photoluminescence. [11][12][13] The structural diversity of borates is justified by the flexibility of boron to adopt either trigonal or tetrahedral coordination, and the diversity of the structure-directing agents.…”
