Geometry optimization

I am trying to build a device for molecular spintronics using nickel and benzene dithiolate. The geometry optimization is almost taking 48 hours on 8 cores and still not converging. Can anybody help? thanks in advance.

Firstly, start with less number of k-points and density mesh cut-off values and then move ahead from there.
Also I think you should relax the structure before making the device.
And try using MPI parallel processes if you haven't already.
