what's the name of this org. compound?
That's supposed to be the sodium salt of salicylaldehyde, also known as sodium salicylaldehyde, sodium ortho-formylphenolate, 2-hydroxybenzaldehyde sodium salt or sodium 2-formylphenoxide. CAS number: 3116-83-4.

There's actually an error in the structure. The oxygen should have a negative charge if the sodium is written with a positive charge. The salt as a whole is neutral. What's written here is one lone pair, there should be 3 of those and a negative charge.
