LTC sent to BTC address

i have one problem, i sent payment of LTC to wrong address (to BTC address). BTC address was generated in Electrum and LTC sent from my Bittrex. I tried to put the seed of the wallet, where i sent the LTC, to the Electrum LTC (but also other wallets) but didn´t work (seed wasn´t loaded). I tried to use the private keys of the payment, but didn´t work too…

Is there something to do with it, please?

Info about payment:
