Abstract

The title complex [Pt(dppe)($NO_3$)($CF_3SO_3$)] (dppe=1,2-bis(diphenylphosphino)ethane, $Ph_2PCH_2CH_2PH_2$) was prepared by sequentially treating [Pt(dppe)$Cl_2$] with 1 equiv of $AgNO_3$ and 1 equiv AgOTf (OTf=$CF_3SO_3$). The Pt metal is coordinated by two phosphorous atoms of the dppe ligand, one oxygen atom of the nitrato ($NO^-_3$) ligand, and one oxygen atom of the triflato(trifluoromethylsulfonato, $OTf^-$) ligand. The coordination sphere of Pt metal can be described as a distorted square plane.

[[Pt(dppe)$Cl_2]$]와 1 당량 $AgNO_3$ 및 1 당량 AgOTf (OTf=$CF_3SO_3$)의 순차적 반응으로 표제 착물 [Pt(dppe)($NO_3$)($CF_3SO_3$)] (dppe=1,2-bis(diphenylphosphino)ethane, $Ph_2PCH_2CH_2PH_2$)이 합성되었다. Pt 금속은 dppe 리간드의 두 P 원자, nitrato ($NO^-_3$) 리간드의 O 원자, 그리고 triflato (trifluoromethylsulfonato, $OTf^-$) 리간드의 O 원자로 배위되어 있다. Pt 금속의 배위권은 일그러진 평면 사각형으로 기술될 수 있다.
