In the crystal Structures, a planar cation of C 7 H 6 N 3 O 2 + , a planar trigonal anion of HgX3– [X = Cl, Br] and water molecule are arranged through the hydrogen bonds of X⋯H–O, O⋯H–N, and X⋯H–N into 2D sheets which are parallel to ac plane. The sheets are connected by
摘要 三种新的卤化汞 (II) 复合盐 [C7H6N3O2] HgX3·H2O (1: X = Cl, 2: X = Br, 3: X = I) 通过化学计量的适当反应物在水性介质中反应合成。通过 FT IR、NQR 光谱和单晶 X 射线衍射进行研究。1和2的晶体结构与正交晶系(Pnma)等构;a = 15.943(5), b = 6.357(6), c = 12.733(7) A, Z = 4 at 296(2) K for 1 and a = 16.104(4), b = 6.539(4), c = 13.059(4) A, Z = 4 在 296(2) K 时分别为 2。在晶体结构中,C 7 H 6 N 3 O 2 + 的平面阳离子、HgX3– [X = Cl, Br] 的平面三角阴离子和水分子通过X⋯H-O、O 的氢键排列⋯H–N 和 X⋯H–N 成平行于 ac 平面的二维表。薄片通过双链
