The templating properties of a diaza-nickel-cis-dithiolate towards triphenylphosphine gold(I), yielding a transoid [Ni(N2S2)·2Au(PPh3)] complex (T. A. Pinder, S. K. Montalvo, A. M. Lunsford, C.-H. Hsieh, J. H. Reibenspies and M. Y. Darensbourg, Dalton Trans., 2014, 43, 138–144) suggested that a suitable analogue of d10-Au(I), i.e., {Ni(NO)}10, could generate a tetrahedral nickel node for a [Ni(N2S2)·2Ni(NO)(X)]n coordination polymer. Monomeric precursors, derived from Feltham's [(Ph3P)2Ni(NO)(Cl)] (R. D. Feltham, Inorg. Chem., 1964, 3, 116–119) produced the bidentate/sulfur-chelated [Ni(N2S2)·Ni(NO)(X)] species with loss of PPh3. Exchange of Cl by azide, N3, in the {Ni(NO)}10 synthon led to the balance of electrophilicity at Ni(NO) and non-covalent (H-bonding and van der Waals) interactions that stabilized the extended chain of bridging sulfurs, in transoid connectivities, between a square planar NiII and a tetrahedral Ni, the latter within the electronic and spin-delocalized {Ni(NO)}10 system. This study defines a new path that creates coordination polymers using metallodithiolates, the success of which, in this case, depends on the highly polarizable {Ni(NO)}10 unit.

一种依赖于可极化镍亚硝基枢纽的硫模板化 Ni-Ni′ 配位聚合物



重氮-镍-顺式-二硫代酸酯对三苯基膦金的模板性质(),产生转型 [Ni(N2S2)·2Au(PPh3)] 络合物(TA Pinder, SK Montalvo, AM Lunsford, CHHsieh, J. H. Reibenspies 和 M. Y. Darensbourg, Dalton Trans., 2014, 43, 138–144)表明,d10-Au() 的合适类似物, {Ni(NO)}10,可以为 [Ni(N2S2)·2Ni(NO)(X)]n 配位聚合物生成四面体镍节点。源自 Feltham 的 [(Ph3P)2Ni(NO)(Cl)] (R. D. Feltham, Inorg. Chem., 1964, 3, 116–119) 的单体前体产生了双齿/硫螯合物 [Ni(N2S2)·PPh 损失的 Ni(NO)(X)] 物种3.在 {Ni(NO)}10 合成子中,叠氮化物 N3 与 Cl 的交换导致 Ni(NO) 和非共价(氢键和范德华)相互作用的亲电性平衡,从而稳定了跨体连接性中方形平面 NiII 和四面体 Ni 之间的桥接硫的延伸链,后者位于电子和自旋离域 {Ni(NO)} 10 系统。 本研究确定了一条使用金属二硫酸盐制造配位聚合物的新途径,在这种情况下,其成功取决于高度极化的 {Ni(NO)}10 单元。
