Are there any authorized and official vinyl or c.d. releases from "The Russian Federation? In particular vinyl releases? Thanks for any detailed help here!
I think the Melodia USSR Greatest Hits is official.
As I live in Moscow I feel qualified to answer this question. Greatest Hits was available back in the day on the Melodia Label and recent releases can be found though not easily. There are a lot of vinyl bootlegs from the 70's and 80's though they are also hard to find here. Generally Queen missed out on Russia to a certain extent although they did have a very big hit with You don't fool me.
I have some Russian Bootlegs if anyone is interested and I can post details here.
Bootlegs or Pirate?
I love pirate releases by other artists. There was a Bowie compilation that was long thought to be a pirate release of official material
:Starman, here (sorry, long link due to Russian characters) https://www.discogs.com/David-Bowie-Starman-%D0%A7%D0%B5%D0%BB%D0%BE%D0%B2%D0%B5%D0%BA-%D0%A1%D0%BE-%D0%97%D0%B2%D0%B5%D0%B7%D0%B4/release/1049294
... but it turned out those random tracks were actually officially licensed by a Russian label.
There was a flexi disc in 7" size with "Jealousy" on one and some russian traditional music on the other side. That was an official release, too, wasn't it? At least a picture of it is shown in the booklet of the Jazz CD from Hollywood Records in the early 90's.
Please have a look:

Polish ones are great too - playable one sided postcards.
