Optimization of the MoSSe alloy?

Hi Dear ABINIT users,

I want to alloy MoS2 compound with Se atom to construct MoS1.5Se0.5. I replaced one of the four S atoms by one Se atom. But, my optimized calculations could not be converged for atomic positions and lattice constants. I have examined some input files, but these input files could not solve my problem. I would you mind suggesting what should I do?
Thank you so much for your kind attention!
Best wishes.
