Reaction between NOSbF6 and Cu(SbF6)2 in aHF yielded NOCu(SbF6)3. In the presence of H3OSbF6, single crystals of (H3O)0.2(NO)0.8Cu(SbF6)3 were grown from a saturated aHF solution. Both salts are isotypic and crystallize in the orthorhombic space group Pnma (No. 62) at 200 K. The main feature of their crystal structures are rings of CuF6 octahedra sharing apexes with SbF6 octahedra connected into 3‐D network. Single charged cations are located inside the cavities. Reaction between 0.25NOSbF6, 0.75NO2SbF6 and Cu(SbF6)2 in aHF yielded (NO)0.25(NO2)0.75Cu(SbF6)3 upon the crystallization. It crystallizes in the cubic space group Imurn:x-wiley:14341948:media:ejic202100139:ejic202100139-math-0001 (No. 204) at 200 K. Subsequent experiments with M(SbF6)2 (M=Cu, Zn) showed that, when the NO+ cations are partially or completely replaced by H3O+, the grown crystals of (H3O)0.125(NO)0.125(NO2)0.75Zn(SbF6)3 and (H3O)0.25(NO2)0.75M(SbF6)3 (M=Cu, Zn) are isotypic to (NO)0.25(NO2)0.75Cu(SbF6)3. Crystal structure of the latter demonstrates similar 3‐D structural motif as observed for the NOCu(SbF6)3 salt. The crystal structures of (H3O)0.64(NO2)0.36CuF(SbF6)2 and [Cu(H2O)6](SbF6)2 were also determined. Crystallizations of NOSbF6/O2SbF6 were carried out in aHF in different molar ratios. The crystal structure determinations of grown single crystals showed that they have the composition (NO)x(O2)1‐xSbF6 (x=0.17, 0.55 0.75) indicating that most likely all phases with x=0–1 exist. They are isotypic to NOSbF6.

新型混合阳离子六氟锑酸盐的氮盐和氮盐(V)

NOSbF 6与Cu(SbF 62在aHF中反应生成NOCu(SbF 63。在H 3 OSbF 6的存在下,从饱和aHF溶液中生长出(H 3 O)0.2(NO)0.8 Cu(SbF 63的单晶。两种盐都是同型的,并且在正交晶空间群Pnma(No. 62)中在200 K时结晶。它们的晶体结构的主要特征是CuF 6八面体的环与SbF 6共享顶点八面体连接到3D网络。单电荷阳离子位于腔体内。0.25NOSbF之间反应6,0.75NO 2的SbF 6和Cu(SBF 62中,产生AHF(NO)0.25(NO 20.75铜(SBF 63时结晶。它 在200 K的立方空间群Im骨灰盒:x-wiley:14341948:media:ejic202100139:ejic202100139-math-0001(No. 204)中结晶。随后用M(SbF 62(M = Cu,Zn)进行的实验表明,当NO +阳离子被H 3 O部分或完全替代时,+,(H 3 O)0.125(NO)0.125(NO 20.75 Zn(SbF 63和(H 3 O)0.25(NO 20.75 M(SbF 63(M = Cu,Zn )与(NO)0.25(NO 20.75 Cu(SbF 63同型。后者的晶体结构表现出与NOCu(SbF 63盐类似的3-D结构基序。(H 3 O)的晶体结构还测定了0.64(NO 20.36 CuF(SbF 62和[Cu(H 2 O)6 ](SbF 62。在aHF中以不同的摩尔比进行NOSbF 6 / O 2 SbF 6的结晶。生长的单晶的晶体结构测定表明,它们的组成为(NO)x(O 21-x SbF 6(x = 0.17,0.55 0.75),表明最可能存在x = 0–1的所有相。它们与NOSbF 6是同型的。
