合成了具有非线性光学特性的标题加合物.以降温法培养出24 mm×15 mm×38 mm大尺寸单晶,该单晶在1064 nm的Nd3+:YAG激光束照射下,产生绿色的532 nm倍频光.以X射线衍射法测定了此1:1加合物的晶体结构,晶体属P1空间群,a=0.4609(2)nm,b=0.7405(5)nm,c=1.0684(6)nm,a=95.50(5)°,β=98.72(3)°,γ=104.33(5)°,Z=1;R=0.076.3,5-二硝基苯甲酸与二乙醇胺之间,以氢键相联,构成平行于001晶面的二维网络. A title adduct with non-linear optical properties was synthesized.The large size single crystal of 24 mm × 15 mm × 38 mm was grown by cooling method and the single crystal was irradiated with Nd3 +: YAG laser beam of 1064 nm to produce green 532 nm. The crystal structure of the 1: 1 adduct was determined by X-ray diffraction. The crystal belongs to the space group P1 with a = 0.4609 (2) nm, b = 0.7405 (5) nm and c = 1.0684 ) nm, a = 95.50 (5) °, β = 98.72 (3) °, γ = 104.33 (5) °, Z = 1; R = 0.076. Between 3,5-dinitrobenzoic acid and diethanolamine, By hydrogen bonding, constitute a two-dimensional network parallel to 001 crystal plane.
