中文摘要	A series of novel noncentrosymmetric borates, MM'(4)(BO3)(3) (M = Na, M' = Ca; M = K, M' = Ca, Sr), have been successfully synthesized via a standard solid-state reaction. The crystal structures have been determined by the SDPD (structure determination from powder diffraction) method. They crystallize in the noncentrosymmetric space group Ama2 with the following lattice parameters: a = 10.68004(11) angstrom, b = 1 1.28574(11) angstrom, c = 6.48521(6) angstrom for NaCa4(BO3)(3); a = 10.63455(10) angstrom, b = 11,51705(11) angstrom, c = 6.51942(6) angstrom for KCa4(BO3)(3); and a = 11.03843(8) angstrom, b = 11.98974(9) angstrom, c = 6.88446(5) angstrom for KSr4(BO3)(3). The fundamental building units are isolated BO3 anionic groups. Their second harmonic generation (SHG) coefficients were one-half (NaCa4(BO3)(3)), one-third (KCa4(BO3)(3)), and two-thirds (KSr4(BO3)(3)) as large as that of KH2PO4 (KDP). The infrared and UV-vis spectra of the three compounds are discussed. Moreover, a comparison of the structures of these novel compounds and three other novel cubic compounds with the same formula, MM'(4)(BO3)(3) (M = Li, M' = Sr; M = Na, M' = Sr, Ba), is presented here.
