Hydrothermal synthesis and characterization of the first mixed alkali borate-nitrate K3Na[B6O9(OH)3]NO3

M3B6O10NO3 (M = K, Rb): Two New Alkali Metal Borate‐Nitrates with Noncentrosymmetric Structures

“…The selected bond lengths and angles of the title compounds are shown in Table S2, which are in the typical ranges of the reported borate-nitrates. [14][15][16][17][18][19][20][21][22] The global instability indices (GII) of these compounds were also calculated, which are derived from the bond valence concepts indicating the strains induced by lattice. [26] The GII values of both compounds are larger than 0.05 v.u.…”

“…The following absorptions in the infrared spectrum was assigned according to previous reports. [14][15][16][17][18][19][20][21][22] The strong absorption peak sited near 1386 cm À 1 is arised from the overlap of the stretching vibrations of trigonal NO 3…”

“…To date, about a dozen borate-nitrates have been fully characterized. Since most of them were synthesized by hydrothermal method, hydrous phases were usually obtained including a series of rare-earth borate-nitrates, [14] and the alkali metal borate-nitrate K 3 Na[B 6 O 9 (OH) 3 ]NO 3 [15] as well as the transitionmental borate-nitrate K 7 Ni[B 18 O 24 (OH) 9 ](NO 3 ) 6 • (H 3 BO 3 ). [16] Unhydrous phases were also obtained via hydrothermal method, for example, Na 3 B 6 O 10 NO 3 , [17] Na 3À x K x [B 6 O 10 ]NO 3 (x = 0.5, 0.6, 0.7), [18] [Pb 3 (B 3 O 7 )](NO 3 ), [19] Pb 6 O 4 BO 3 NO 3 [20] and Pb 2 (BO 3 )(NO 3 ).…”

Serendipitous formation and characterization of K2[Pd(NO3)4]·2HNO3

“…Further promising candidates are heteroleptic compounds with different anionic species like Sn 3 [B 3 O 7 ]F [2] and Pb 3 B 6 O 11 F 2 [3]. With the synthesis of K 3 Na[B 6 O 9 (OH) 3 ]NO 3 [4]…”
