structures. The salts [(Et3P)Au(bipy)]XF6 (X = P, As, Sb) form a second isostructural series. In this series the unsymmetrical coordination of the bipy ligand is maintained, but the gold ions are disordered over two unequally populated positions that produce very similar overall structures for the cations. Although many planar, three-coordinate gold(I) complexes are strongly luminescent, the salts [(R3P)Au(bipy)]XF6
通过晶体学和计算研究已经研究了
2,2'-联吡啶(bipy)在某些平面三坐标阳离子中
金(I)的不对称配位。盐[(Ph3P)Au(bipy)] XF6(X = P,As,Sb)形成一个同构系列,其中Au-N距离的差范围为0.241(2)至0.146(2)。还发现了[(Ph3P)Au(bipy)] AsF6的第二个多晶型物。两种多晶型物表现出相似的结构。盐[(Et3P)Au(bipy)] XF6(X = P,As,Sb)形成第二个同构系列。在该系列中,维持了Bipy
配体的不对称配位,但是
金离子在两个不等密度的位置无序排列,产生了非常相似的阳离子整体结构。尽管许多平面的三配位
金(I)配合物具有很强的发光性,但盐[(R3P)Au(bipy)] XF6(R = Ph或Et; X = P,As,Sb)不以固体或溶液形式发光。计算研究表明,[(Et3P)Au(bipy)] +的完全对称结构比观察到的不对称结构的能量高7
