There's this rockabilly chord I want to identify.

I've often heard this chord used by Carl Perkins. When the Beatles were going through their country phase, they used this chord to end a song. Very cool uplifting chord for an ending. I know it's not much to go on, but does anyone know what chord I am referring to?

If you can think of one or two of the Beatles songs where they've ended on this chord, it would help. Even a lyric...

A sixth chord? Fer instance: E6 0-2-2-1-2-0

You might be thinking of x-x-11-11-12-12 (assuming the song is in E). Sounds good with a slight wiggle of the tremelo arm if you have one.

Apparently it goes by the name of E/C# 6th Suspended 2nd

Not much to go on here but I would wager a 6/9 chord. The poster above gave the tab as

-12- or -12-
-12- -12-
-11- -11-
-11- -11-
--x- --x-
--x- -12-

And this works, as does

-7- or -7-
-7- -7-
-6- -6-
-6- -6-
-x- -7-
-x- -x-

Both of these could be E6/9 chords. These are very common ending chords in jazz, rockabilly and blues. Even Stevie Ray Vaughan uses them (to much better effect than I do)

And what about

-7-
-6-
-5-
-5-
-x-
-x-

?

The moveable XX2233 chord also sounds like a X5678X chord, they're pretty much interchangeable. Category "jazz chords" i.e. I have no idea what the names are.
But they make do good ending chords

Wow, they really are making this harder than it is. It is an E6/9. You don't have to leave the C# on the bottom - it's easy to grab the 12th fret low E along with the rest of the chord you posted.
