to as ptt (platinum triazine) agents. The X-ray structures of three LPtCl2 compounds revealed the expected pseudo-square-planar geometry. The X-ray structure of [(pyPh2t)2Pt](BF4)2 [pyPh2t = 3-(pyridin-2'-yl)-5,6-diphenyl-1,2,4-triazine] has the expected trans relationship of the unsymmetrical L and is essentially planar, an unusual property for a Pt(II) complex with two bidentate sp2 N donors.

合成了LPtCl2和[L2Pt] X2类型的络合物[L =取代的3-(吡啶-2'-基)-1,2,4-三嗪],并通过NMR光谱进行了表征,并首次通过X-射线晶体学,以确定这种新型的具有HIV-1杀灭病毒活性的无机药物的配位性质。包含一个或两个sp2 N-供体双齿配体的试剂称为ptt(三嗪铂)试剂。三种LPtCl2化合物的X射线结构揭示了预期的伪正方形平面几何形状。[[pyPh2t)2Pt](BF4)2 [pyPh2t = 3-(吡啶-2'-基)-5,6-二苯基-1,2,4-三嗪]的X射线结构具有预期的反式关系不对称L,并且基本上是平面的,这是具有两个双齿sp2 N供体的Pt(II)配合物的不寻常特性。HIV-1是一种RNA病毒;鸟苷核糖核苷(Guo)在两个(等价)可用的配位点上结合(MepyMe2t)PtCl2,形成[(MepyMe2t)Pt(Guo)2] 2+ [MepyMe2t = 3-(4'-甲基吡啶-2'-yl)-
