For others reading this issue, the h5netcdf workaround was discussed in #3297, with further discussion on supporting complex numbers in netCDF in cf-convention/cf-conventions#204.

The short version: engine="h5netcdf", invalid_netcdf=True will save these files, but the netCDF-C library doesn't understand the result. Reading with engine="h5netcdf" may be able to round-trip these files, but I haven't checked that.

There is a longer discussion of why netCDF-C doesn't understand these files at Unidata/netcdf-c#267. That specific issue is for booleans, but complex numbers are likely the same.
