| 摘 要： | Two fluoride sulfates,K2Mn3(SO4)3F2·4H2O(Ⅰ) and Rb2Mn3(SO4)3F2·2H2O (Ⅱ) are obtained by water solution method.Single-crystal X-ray diffraction analysis indicated that they crystallize in space groups of Cmc21.Their structures feature a pseudo-KTP structure consisting of interconnectingMn3(SO4)3F2(H2O)2]∞ layers,which are further packing along the a axis with alkali metal cations balancing the charges.The structure relationships between the two compounds are discussed.Secondharmonic generation measurements manifest that Ⅰ and Ⅱ have similar second-harmonic generation responses of about 0.2 and 0.25 times that of KH2PO4.

| Abstract: | Two fluoride sulfates, K2Mn3(SO4)3F2·4H2O (I) and Rb2Mn3(SO4)3F2·2H2O (Π) are obtained by water solution method. Single-crystal X-ray diffraction analysis indicated that they crystallize in space groups of Cmc21. Their structures feature a pseudo-KTP structure consisting of interconnecting Mn3(SO4)3F2(H2O)2]∞ layers, which are further packing along the a axis with alkali metal cations balancing the charges. The structure relationships between the two compounds are discussed. Second-harmonic generation measurements manifest that I and Π have similar second-harmonic generation responses of about 0.2 and 0.25 times that of KH2PO4. |
