The titular compound [K([2.2.2]-crypt)]K[Pt3(μ2-CO)3(PPh3)3] ⋅ 3NH3 (1) ([2.2.2]-crypt=4,7,13,16,21,24-Hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane) contains a triangular platinum complex, the approximate D3 symmetry of which is only broken by the phenyl substituents of the PPh3 ligands.. The dianionic complex represents only the second triangular carbonyl platinate characterized via single crystal X-ray
标题化合物 [K([2.2.2]-crypt)]K[Pt 3 (μ 2 -CO) 3 (PPh 3 ) 3 ] ⋅ 3NH 3 ( 1) ([2.2.2]-crypt=4,7 ,13,16,21,24-Hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane) 包含一个三角形铂络合物,其近似D 3对称性仅被 P Ph 3配体的苯基取代基打破。 . 双离子络合物仅代表通过单晶 X 射线衍射以单体形式表征的第二个三角形羰基铂酸盐。该化合物在空间群 P 中结晶晶胞参数 a=13.8826 Å、b=14.2899 Å 和 c=21.3254 Å。对于铂酸盐的形成,液氨似乎起着至关重要的作用,作为用于还原和稳定二价阴离子的多锗化物的溶剂。
