Why KHF2, is exist but KHCI2, is not?

1.	Why KHF2, is exist but KHCI2, is not?
Answer» F is much more electronegative than Cl hence has much stronger hydrogen bonding, which stabilizes the structure with FA mixture of molten KF and HF is hence chemically K+ [HF2]- and is used in moisson method to extract F2 which was chemically almost impossible. Further, [HF2]- involves strongest symmetric 3c-4e hydrogen bonding.
