Has there ever been a show about a mixed-gender group of adult friends where there are no romantic entaglements within the group?

Brian almost definitely slept with Marsha. As best as I remember from subtext and possibly the DVD extras, he was behind on rent, and Marsha made an indecent proposal. Add that to the fact that he's hung like a horse and you understand why Marsha might retain some interest.

Also, Tim and Daisy do eventually get together, but officially only after the series ends. Tyres saw what was going on a lot sooner than that though.

Finally, there's the potential that Mike might actually have more than a man-crush on Tim. They have a bromance, sure, but there might be other things going on in Mike's head that Tim is completely oblivious to.

Good one, I hadn't thought of that

The original Power Rangers were teenagers. And I thought Jason and Kimberly were a couple but I don't know, the only season I really watched was RPM, which has a romance between Dillon and Summer

Only Murders in the Building I agree on but Abbott Elementary has romance between Gregory and Janine. The Orville has romance between Isaac and Claire and arguably Ed and Kelly (exes who seem to still have feelings for eachother) I can't comment on your other examples, I haven't seen them

New girl, nick and jess, Schmidt and CeeCee. People hook up in that show.

Didn't know there was an American one tbh

I read that as Velma and Scooby. Oops.

Yeah, I don't think it's even mentioned in the next episode

Me in my dreams hnnnnnnnng

Oh I only watched like four episodes

They even recycled a lot of the same basic characters and plot points. It's has a pretty different feel though, so I'm not sure whether to be mad.

You had to see that coming OP.

OPs examples have one couple but still other friends.

There are also French, German, Greek, and Australian versions

Seems like that depends on a group of screenwriters with a masochistic enjoyment of denial. You have to think it would be a very tempting subplot to start.

As a result, most of the ideas people here have involve like three main characters. I'm not sure about 30 Rock.
