Mercury基操-输出透明背景结构图

如图1所示，最近有小伙伴在微信上留言询问Mercury [1]如何导出透明背景晶体结构图，这样就可以在ChemDraw [2]中插入无背景晶体结构图。

▲图1 问题描述

本文以Olex2 [3]内置晶体数据Sucrose [4]为例，首先将其CIF [5]文件sucrose.cif用Mercury打开，设置好模型样式，例如椭球模型，然后调整好视图角度和模型大小，如图2所示。

▲图2 Mercury打开sucrose.cif文件并设置模型样式和视图角度

然后在顶部菜单File下拉菜单中选择Save As…（或者按Ctrl+S组合快捷键），如图3所示。

▲图3 File>>Save As…

然后在弹出的“另存为”对话框中保存类型下拉菜单中选择要导出图片的类型，例如本文选择TIFF，如图4所示。

▲图4 导出图片类型选择

选好类型后，点击右下角保存按钮，弹出如图5所示“Save Image”对话框，在底部有一个“Transparent background”（透明背景）复选框，勾选该复选框即可导出透明背景图片。

▲图5 透明背景复选框

导出的两个图片文件（上为sucrose.tif，下为sucrose-transparent.tif）如图6–8所示，白色背景和透明背景一目了然。

▲图6 导出的白色背景和透明背景图片

▲图7 白色背景图片

▲图8 透明背景图片

在ChemDraw顶部菜单Edit下拉菜单中选择Insert File…（插入文件），如图9所示。

▲图9 Edit>>Insert File…

在弹出的“打开”对话框中，在文件类型下拉菜单中选择TIFF Image，如图10，找到Mercury导出的图片，将其导入ChemDraw。

▲图10 选择要导入的文件类型

如图11所示，白色背景晶体结构图会遮挡结构式（当然，将其图层调至底层亦可显示结构式），而透明背景晶体结构图则不会遮挡结构式。

▲图11 最终效果
