摘要
以哌嗪、亚硒酸和卤化锰为原料，在水溶液中合成了两种新型有机阳离子络合氢亚硒酸盐（C4H12N2）[Mn(HSeO3)2Cl2](1)和[(C4N12N2)Br]2[Mn(HSeO3)2Br2](2)单晶。通过单晶x射线衍射分析确定了1和2的晶体结构；它们具有单斜对称性(1:P21/c, a = 9.7557(7) Å， b = 7.3930(5) Å， c = 9.7660（6) Å， β = 116.839(7)°）；2: P21 / c, a = 14.4093 (3), b = 7.3822 (1) a, c = 10.3051(3),β= 101.553(2)°)。这两种化合物的晶体结构都是由[Mn(HSeO3)2X2]2 - (X = Cl, Br)组成的层和由哌嗪阳离子组成的层交替构成的。化合物1是前面所述化合物（C4H12N2）[Cd(HSeO3)2Cl2]的结构类似物，而化合物2的晶体结构属于一种新的结构类型，具有模块结构的特点，并且含有含有哌嗪阳离子和溴阴离子的层。
Synthesis and Crystal Structures of (C4H12N2)[Mn(HSeO3)2Cl2] and [(C4N12N2)2Br]2[Mn(HSeO3)2Br2]—New Representatives of the Modular Family of “Layered Hydroselenites”
Single crystals of two new complex hydroselenites with organic cations—(C4H12N2)[Mn(HSeO3)2Cl2] (1) and [(C4N12N2)Br]2[Mn(HSeO3)2Br2] (2)—were obtained as the products of the reaction of piperazine, selenious acid, and manganese halide in an aqueous medium. The crystal structures of 1 and 2 were determined by single-crystal X-ray diffraction analysis; they are characterized by monoclinic symmetry (1: P21/c, a = 9.7557(7) Å, b = 7.3930(5) Å, c = 9.7660(6) Å, β = 116.839(7)°; 2: P21/c, a = 14.4093(3) Å, b = 7.3822(1) Å, c = 10.3051(3) Å, β = 101.553(2)°). The crystal structures of both compounds are constructed by alternating layers of the composition [Mn(HSeO3)2X2]2– (X = Cl, Br) and layers formed by piperazinium cations. Compound 1 is a structural analogue of the previously described compound (C4H12N2)[Cd(HSeO3)2Cl2], while the crystal structure of compound 2 belongs to a new structural type, is characterized by a modular structure, and contains layers including both piperazinium cations and bromine anions.
