spectra of the series [M(NSF3)4(AsF6)2](M = Mn, Fe, Co, Ni, or Cu) indicate that the compounds are isostructural, with trans-AsF6 groups co-ordinated to the metal atom, and N–S bonds appreciably stronger than in free NSF3. This is confirmed by the crystal structure of trans-[Mn(NSF3)4(AsF6)2]. It crystallises in the monoclinic space group P21/n, with a= 7.496(4), b= 10.378(5), c= 13.979(6)Å, β= 94.33(3)°
系列[M(NSF 3)4(AsF 6)2 ](M = Mn,Fe,Co,Ni或Cu)的红外光谱表明,这些化合物是同构的,反式-AsF 6基团与金属原子和N–S键比游离NSF 3明显更强。反式-[Mn(NSF 3)4(AsF 6)2 ]的晶体结构证实了这一点。它在单斜空间群P 2 1 / n中结晶,其中a = 7.496(4),b = 10.378(5),c= 13.979(6)Å,β= 94.33(3)°,并且Z= 2。对于1226个衍射仪数据,将结构改进为R= 0.048。金属离子与Mn-N av八面体配位。2.187,Mn–F 2.193(4)和N–s av。1.365Å。
