There is not a standard way (it would be nice if there was one). The
usual thing is to save them as a compound datatype, but people choose
different options for the names of the fields. Here are what I know:
* ("real", "imag") for Octave
* ("r", "i") for PyTables (but ("real", "imag") is ok too)

May be there is a possibility to define an atomic datatype in HDF5, but
provided that you don't introduce padding between the fields of the
compound type, this works pretty similar to a larger, atomic type.
Hope this helps,
