Saljut 1 was the first russian Orbitalstation which has been launched on 19 of april 1971.
Only two Sojus missions visited the Orbitalstation, Sojus 10 and Sojus 11.
Totally the russians constructed and launched 8 different Orbitalstations, 7 Saljutstations (1 to 7) and the Mirstation, which was the most advanced one.
Saljut 1 had a weight of around 19 tons, 3 times more than a Sojus spaceship and had 10 times more space than the Sojus spaceship.
After the disaster of Sojus 11 with the death of the three cosmonauts, the Saljut 1 Orbtilastation never got more visits of Sojusmissions.
The next Orbitalstation was Saljut 2.
Saljut 2 was launched 3rd of april 1973 , but never got visits from Sojus missions.
The second Orbitalstation from Russia got fire and was destroyed in the orbit after some days in space.
On 28 of april the main parts of the destroyed orbitalstation entered the atmosphere of Earth and disappeared.

Two days after lauch docking with Saljut 1 but not totally successful
The distance between Sojus 10 and Saljut 1 was calculated to 9 cm, no transfer of the crew to the Orbitalstation was possible
