I put together a program that might embody what you are doing.
Does it convey what you are trying to do?

#include <stdlib.h>
#include <stdio.h>
#include <netcdf.h>
#include <string.h>

/* The data file we will create. */
#define FILE_NAME "t.nc"
#define NDIMS 2
#define NX 2
#define NY 2

static const char* data[4] = {"abc", "def", "ghi", "jkl"};

static void
fail(int ret)
{
    fprintf(stderr,"fail: %d:%s\n",ret,nc_strerror(ret));
    exit(1);
}

int
main(int argc, char **argv)
{
    int ret = NC_NOERR;
    int ncid, varid;
    int dimids[NDIMS];
    
    if((ret=nc_create(FILE_NAME, NC_CLOBBER|NC_NETCDF4, &ncid)))
        fail(ret);
    
    if((ret=nc_def_dim(ncid, "nx", NX, &dimids[0])))
        fail(ret);
    if((ret=nc_def_dim(ncid, "ny", NY, &dimids[1])))
        fail(ret);
    
    if((ret=nc_def_var(ncid, "var", NC_STRING, NDIMS, dimids, &varid)))
        fail(ret);
    
    if((ret=nc_enddef(ncid)))
        fail(ret);
    
    if((ret=nc_put_var(ncid, varid, data)))
        fail(ret);
    
    if((ret=nc_close(ncid)))
        fail(ret);
    
    return 0;
}
