Has there ever been a truly communist state as Marx would have wanted?

No, because Marx viewed the state as a bourgeois construction aimed at oppressing the proletariat. He and Engels argue in the Communist Manifesto that

>Through the emancipation of private property from the community, the State has become a separate entity, beside and outside civil society; but it is nothing more than the form of organisation which the bourgeois necessarily adopt both for internal and external purposes, for the mutual guarantee of their property and interests.

and

>The executive of the modern state is nothing but a committee for managing the common affairs of the whole bourgeoisie

Essentially, he held the view that the 'state' existed in relation to capitalism, feudal pre-capitalist, capitalist, and lastly post-capitalist. In the post-capitalist phase, he argued that the state would disappear for lack of purpose.

In a letter to Mikhail Bakunin, he and Engels say,

>As, therefore, the state is the chief evil, it is above all the state which must be done away with and then capitalism will go to hell of itself. We, on the contrary say: do away with capital, the appropriation of the whole means of production in the hands of the few, and the state will fall away of itself. 

So no, no state has ever been 'truly communist' as Marx would have wanted, simply because Marx's revolution would have precluded the need for such a structure.
