I add to this issue as it refers to general IO failures. Saving a Dataset that contains DataArray with complex data-type fails on all netCDF4 engines:

dataset = xr.Dataset({'data': np.zeros((2,), dtype='complex128')}) dataset.to_netcdf('tmp.nc', engine='netcdf4') [...] TypeError: illegal primitive data type, must be one of dict_keys(['i8', 'f4', 'f8', 'i2', 'u2', 'i1', 'i4', 'S1', 'u8', 'u1', 'u4']), got complex128

and

dataset.to_netcdf('tmp.nc', engine='h5netcdf') [...] TypeError: Object dtype dtype('O') has no native HDF5 equivalent
