D2O has different bond angles relative to H2O, basically, and it forms a crystalline structure less dense than liquid H2O.

D2O also doesn't hydrogen bond as tightly.  It also is toxic (in high doses) because of the secondary isotope effect which I won't bore you with.

If regular water was dense than ice, we probably would not have life on the planet.  Oceans would freeze from the bottom up and kill everything in it.  The water deep in the ocean gets to 4°C because that is the densest point for H2O.
Does frozen deuterium oxide float in liquid deuterium oxide?

Per the Font of All Wisdom and Knowledge, its temperature of maximum density is 11.6°C.

It will float in D2O liquid water.

It is a clever way to kill someone.

Problem is finding enough deuterium, I'm guessing...

We used quite a bit of D2O back in the day as an NMR solvent.  (Mostly we used CDCl3 really.)

You can buy it, it's a bit pricey.  But you need to feed it to a person for a few weeks and ensure they don't get any regular water from food or drinking.  An ME would be unlikely to check on levels of D in the body, that would take running a mass spec.

A Mass spec is a fascinating piece of equipment these days.
