铟硼磷酸盐结构中的交叠生长规律研究
Several indium borophosphates have been reported recently, including KIn[BP2O8(OH)]( Ⅰ ) and NaIn[BP2O8(OH)]( Ⅱ ). The latter two compounds were synthesized under mild hydrothermal conditions, and have the samemolar ratio (MⅠ:In:B:P:O:H) in molecular formula but with different structure types. Compound Ⅰ crystallizes inthe 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=0.3573 nm3, Z=2; while compound Ⅱ possesses a monoclinicstructure with space group P21/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) nm3, Z=4. Eight-membered-ring and six-membered-ring are formed by alternating borate, phosphatetetrahedra and In-coordination octahedron sharing corners via common oxygen atoms in compound Ⅰ and Ⅱrespectively. The polyhedra in the structure are oriented along certain direction to form alternating layeredfragments. These two structure types can be considered as intergrowth structures, which consist of the samelayered fragments growing in different orientations. Other structure intergrowth possibilities are also expected insimilar systems. CSD: Ⅰ, 409583; Ⅱ, 413343.
