摘　　要：Several indium borophosphates have been reported recently,including K In[BP 2 O 8 (OH)]( Ⅰ )and NaIn[BP 2 O 8 (OH)]( Ⅱ ).The latter two compounds were synthesized under mild hydrothermal condit ions,and have the same molar ratio(M Ⅰ ∶In∶B∶P∶O∶H)in molecular formula but with different structure types.C ompound Ⅰ crystallizes in the triclinic system with space group P1(No.2), a =0.52638(4)nm, b =0.84791(5)nm, c =0.81469(9)nm,α=91.1741(7)°,β=93.061(7) °,γ=79.823(5)°, V =0.3573nm 3 ,Z=2;while compound Ⅱ possesses a monoclinic structure with space group P 2 1 / n (No.14)with a =0.5177(1)nm, b =1.6815(3)nm, c =0.7684(2)nm,β=94.10(3)°, V =0.6672(2)nm 3 ,Z=4.Eight-membered-ring and six-membered-ring are formed by alterna ting borate,phosphate tetrahedra and In-coordination octahedron sharing corner s via common oxygen atoms in compound Ⅰ and Ⅱ respectively.The polyhedra in the structure are oriented along certain dire ction to form alternating layered fragments.These two structure types can be co nsidered as intergrowth structures,which consist of the same layered fragments growing in different orientations.Other structure intergrowth possibilities are also expected in similar systems.CSD: Ⅰ ,409583; Ⅱ ,413343.Several indium borophosphates have been reported recently,including K In[BP 2 O 8 (OH)]( Ⅰ )and NaIn[BP 2 O 8 (OH)]( Ⅱ ).The latter two compounds were synthesized under mild hydrothermal condit ions,and have the same molar ratio(M Ⅰ ∶In∶B∶P∶O∶H)in molecular formula but with different structure types.C ompound Ⅰ crystallizes in the triclinic system with space group P1(No.2), a =0.52638(4)nm, b =0.84791(5)nm, c =0.81469(9)nm,α=91.1741(7)°,β=93.061(7) °,γ=79.823(5)°, V =0.3573nm 3 ,Z=2;while compound Ⅱ possesses a monoclinic structure with space group P 2 1 / n (No.14)with a =0.5177(1)nm, b =1.6815(3)nm, c =0.7684(2)nm,β=94.10(3)°, V =0.6672(2)nm 3 ,Z=4.Eight-membered-ring and six-membered-ring are formed by alterna ting borate,phosphate tetrahedra and In-coordination octahedron sharing corner s via common oxygen atoms in compound Ⅰ and Ⅱ respectively.The polyhedra in the structure are oriented along certain dire ction to form alternating layered fragments.These two structure types can be co nsidered as intergrowth structures,which consist of the same layered fragments growing in different orientations.Other structure intergrowth possibilities are also expected in similar systems.CSD: Ⅰ ,409583; Ⅱ ,413343.
