The charge-neutral organoplatinum(II) complexes herein,
namely [4-R1-(N^C^N)PtC\3CC6H4-4’-R2] (1–8, N^CH^N=
1,5-bis(2’-pyridyl)benzene), were prepared in quantitative
yields by stirring the corresponding precursor, [4-R1-
(N^C^N)PtCl] (R1=CF3,[10g] H,[13a] or CH3
[13b]), and an
excess of aryl acetylene in methanol in the presence of
NaOH for one day at room temperature.[14] It is notable that
when R1 is CF3, the solids of complexes 1–6 display various
colors, depending on the substituent R2 on the aryl acetylide
ligand (Scheme 1). When R2 is an electron-withdrawing group
(CF3 for 5 and NO2 for 6), an electron-donating group (OCH3
for 3 and N(CH3)2 for 4), or a relatively neutral group (H for 1
and F for 2), the solid is bright yellow, deep red, or dark green
in color, respectively. When R1 is H or CH3, no such color
contrast was observed upon varying R2 from electron-withdrawing
to -donating groups; the solids are yellow in color, as
depicted for complexes 7 and 8 in Scheme 1.
Colors of organoplatinum(II) complexes in the solid state
are usually associated with intermetal interactions.[15] Various
packing modes have been identified by X-ray crystallography
for crystals of complexes 1 (Figure 1), 4 (Figure S1 in the
Supporting Information), and 7 (Figure S2 in the Supporting
Information), which appear as green, red, and yellow solids,
respectively.[16] The salient features in the crystal structures of
both 1 and 4 are the intermolecular PtII···PtII/p–p and
C\2H···p(C\3C) interactions in an orthogonal configuration.

固态下有机铂(II)络合物的颜色通常与金属间互作用相关[15].对于络合物1(图1)、4(支持信息中的图S1)和17(支持信息中的图S2)的晶体,各种不同封装模式已用X射线检晶仪鉴别,它们分别显示为绿色、红色和黄色的固体[16].络合物1和4的突出的特点是在正交结构中分子间PtII…PtII/π-π和C-H…π(C≡C)互作用的体现.
