CDXML Name:SymbolType
CDX Constant Name:kCDXProp_Symbol_Type

First written/read in:ChemDraw 4.0
Required?No

Description:

The type of symbol object.

In CDX files produced by ChemDraw 8.0, this property was mistakenly written as a 1-byte INT8 value. When reading CDX files, if the size of this property is found to be 1 byte instead of the expected 2 bytes, the actual value should be interpreted as actualType = (INT16)savedType. CDX format interpreters that follow the best practices for reading integer values from CDX files will handle this error automatically. ChemDraw returned to writing INT16 values starting with version 8.0.6.

This is an enumerated property. Acceptible values are shown in the following list:
Value CDXML Name Description
0 LonePair LonePair
1 Electron Electron
2 RadicalCation RadicalCation
3 RadicalAnion RadicalAnion
4 CirclePlus CirclePlus
5 CircleMinus CircleMinus

7 DoubleDagger DoubleDagger
8 Plus Plus
9 Minus Minus
10 Racemic Racemic
11 Absolute Absolute
12 Relative Relative
