Two coordination polymers with the heterofunctional ligand 4-PPT (4-(pyridin-4-yl)pyrimidine-2-thiol), [Ni(4-PPT)2]·2(DMF)}n (1) and [Cu2(4-PPT)2]·2(DMF)}n (2), have been isolated by reaction with Ni(OAc)2 and CuBr2, respectively. 1 shows a two-dimensional (2-D) layered structure with a 4-connected sql topology wherein the 4-PPT ligand exhibits a uniform μ2-1, κS κN(pyrimidine): 2, κN(pyridine) bridging
具有杂官能配体4-PPT(4-(吡啶-4-基)嘧啶-2-硫醇),[Ni(4-PPT)2 ]·2(DMF)} n(1)和[通过分别与Ni(OAc)2和CuBr 2反应分离出Cu 2(4-PPT)2 ]·2(DMF)} n(2)。1示出了一个二维(2-d)的层状结构与4连接的SQL拓扑,其中所述4-PPT配体显示出均匀的μ 2 -1,κSκN (嘧啶):2,κN(吡啶)桥接模式。2还具有一个基于独特Cu I 4 S 4簇的sql网络,其中4-PPT配体采用两种配位模式,即。μ 3 -1,κN (嘧啶):2,3,κS和μ 4 -1,κN (嘧啶):2,3,κS:4,κN (吡啶)。为了进行比较,CuBr 2与3-PPT(4-(P吡啶基-3-基)嘧啶-2-硫醇(4-PPT的异构体))在相同条件下也进行了检测,得到了具有6 3 - hcb拓扑结构的[CuBr(3-ppds)] n(3)(3-ppds
