Recent advances in crystalline hydrated borates with non-metal or transition-metal complex cations

“…A third  configuration, in which the -interactions are R2 2 (12) (reciprocal-), has also been observed [18,48,64,69,70]. The  configuration, with a R2 2 (8) reciprocal- H-bond interaction, is also known [41,75]. There has been one case of an configuration, [ These pack as rectangles (six pentaborates) in planes in either (a) brickwall or (b) herringbone arrangements [43,76].…”

“…The majority of compounds described in this review have been prepared in aqueous solution by simply mixing reactants [10,[16][17][18][19]25,27,31,[39][40][41][43][44][45]48,50,52,54,56,59,62,75,87,93,95,96,100] or by use of hydrothermal [20,22,26,28,30,32,34,37,47,53,57,[63][64][65][70][71][72]79,82,84,102,115] or solvothermal [35,3...…”

“…However, the  acceptor site configuration is particularly common and two variants of this configuration, both with C(8) -interactions, have been described [43,76,77]. These structures are referred to as 'herringbone' [35,36,[38][39][40][41]43,48,57] or 'brickwall' [37,41,43,45,52,75] (Figure 7). A third  configuration, in which the -interactions are R2 2 (12) (reciprocal-), has also been observed [18,48,64,69,70].…”

Structural Regulation and Oxygen Reduction Reaction Activity of [Co(bpy)2BO2(OH)] and [Cu(bpy)(OH)]2– Complex Templated Borates

“…The synthesis and design of templated borate crystals have attracted considerable interest from scientists due to their flexible structure and various potential applications in ion exchange, nonlinear optics, and catalysis. − B can be bonded with O to form BO 3 and BO 4 units, which are the primary building units of borates. If these two kinds of units connect with each other by shared O atoms, different polyanions could be formed, as is known, some of which have been reported, such as [B 3 O 3 (OH) 4 ] − , [B 4 O 5 (OH) 4 ] 2– , and [B 5 O 6 (OH) 4 ] −- . More importantly, these units can polymerize in pairs to produce polyatomic clusters .…”
