I would be grateful if anyone has any experience of this strange (to me) nut and whether standard tools will grip it or if I need to buy a tool, what do I ask/look for exactly?
I'm tempted to jam on a deep socket but I don't want to round it off or damage my socket so I then thought of using a pair of mole grips or similar but there's not enough swinging room for those.
Any advice gratefully received.

Looks like a Torx socket is what you need.
There are a few variants of torx sockets and keys according to purpose. Some have a fine pattern with a large count of tooths others have a more course pattern. Looks like the latter is the one.
Unfortunately a standard socket will have a 6 or 12 edge pattern, while the Torx usually have an 8 edge pattern. So it might not be do-able with a standard socket.
But if you dont try, you will never win ... 8)

Looks like a multi sided nut so a normal spanner could work, some cars use the same type for big end nuts.

I've seen these on turbo's and manifolds as a deterrent anti tamper
fastening; of course there's every chance you can buy just the tool
for the job which kind of defeats the objective in the first place.
I'm sure no conventional fastening socket/wrench will be safe to use any
kind of torque with and jamming a socket on may make removal a whole
lot worse than it currently looks.

Thank you kindly for your suggestions gentlemen
I should have mentioned there are no sharp teeth on it like a torx and the relief is quite shallow not to mention the small size considering the force I'll have to use to break the corrosion. I'll see if I can source a socket Monday, as you say, I have to try something.
Yes, it's on the turbo, the only one of three bolts that have this nut and it's the bolt that fixes a support brace to the block which is the only reason I want it off.

I recently came across these nuts on the exhaust manifold of the CT Turbo estate Jim and I broke for parts.
I've just checked for fit on a few that I saved and found that a good quality (ie Facom is a closer fit than Halfords Professional) 10mm 12 point socket/ring spanner or a Torx 16 socket fits equally as well.

12 point should be a normal socket or ring spanner, the same type of nuts are used on many exhaust manifolds/turbochargers, Rover's use the same design nut but in 10mm format and they come undone fine.
