Syntax:
bond=typeDefines the specific type of the connection (see Bond Types) required for a bound atom. The keyword should be used inside bracketed parts of bound atom descriptions. It is important to note that the 'bond' keyword should only be used in conjunction with the '~X' (any bond to) specifier, since the specific connection demanded by the '-X' and '=X' specifiers will override any 'bond' declarations.
For example:
Table 8.5. NETA keyword 'bond' examples
| Command | Meaning |
|---|---|
| ~O(bond=double) | A double bond to an oxygen atom (equivalent to '=O') |
| ~&55(bond=triple) | A triple bond to an atom which matches type ID 55 (see reusing types) |
| ~C(bond=single) | A single bond to a carbon atom (a very explicit way of writing simply '-C') |
