摘要

首次获得了四齿（N2O2）席夫碱(L)和双氰金属酸盐[Mn(L)M(CN)2]n配合物的单晶，其中L = Salpn2 - = n, n '-双（水杨基）-1,3-二氨基丙烷，M = Ag+ (I), Au+ (II)。通过x射线衍射（CCDC no. 1）测定了I和II的分子结构。2351118 （i), 2351119 (ii)）。结果表明，在这些化合物的晶体结构中，双氰金属酸阴离子[M(CN)2]是将Mn（III）基团与席夫碱结合成一维结构的桥梁。利用量子化学计算，在C-H…Ag/Au接触点附近发现了（3,-1）型临界点；这证明了这些原子之间存在弱氢键。

Heterometallic Manganese(III) Coordination Polymers with Schiff Bases (H2SALPN) and Dicyanometallates

Single crystals of the Mn(III) complexes with tetradentate (N₂O₂) Schiff bases (L) and dicyanometallates [Mn(L)M(CN)₂]_n, where L = Salpn^2– = N,N'-bis(salicylidene)-1,3-diaminopropane, M = Ag⁺ (I), Au⁺ (II), were obtained for the first time. The molecular structures of I and II were determined by X-ray diffraction (CCDC no. 2351118 (I), 2351119 (II)). It was found that the dicyanometallate anion [M(CN)₂]ˉ in the crystal structure of these compounds acts as a bridge binding the Mn(III) moieties with the Schiff base into 1D. Using quantum chemical calculations, the (3, –1) type critical points were found near the C‒H…Ag/Au contact; this attests to the existence of weak hydrogen bonds between these atoms.
