"With today's signatures, the memorandum of understanding is now in effect," Pentagon press secretary Peter Cook told reporters. "That was signed a short time ago, earlier today."
Separately, Russian media reported that the memorandum had been signed by officials in Moscow and the United States.
"The memorandum contains a number of rules and restrictions aimed at preventing incidents between American and Russian plans," Deputy Defense Minister, Anatoly Antonov said, according to Ria-Novosti.
The United States is leading a 60-plus member coalition targeting Islamic State jihadists in Iraq and Syria and has been carrying out frequent raids for more than a year.
Russia also claims to be targeting IS and other "terrorists" but the Pentagon says it is hitting non-IS rebels fighting government forces loyal to President Bashar al-Assad.
