Can Catholics recieve Communion in a Russian Orthodox church?

[GDTheophilus]

It was my understanding that Catholics could recieve a valid Eucharist in any Orthodox church if necessary (valid holy orders/apostolic succession and sacraments). A friend says that is only true of the Greek Orthodox and then only in a real emergency. My situation was being in Moscow with no idea where to find a Catholic church, but having been given directions to an Orthodox one.

The Code of Canon Law states:

Whenever necessity requires or a genuine spiritual advantage commends it, and provided the danger of error or indifferentism is avoided, Christ’s faithful for whom it is physically or morally impossible to approach a Catholic minister, may lawfully receive the sacraments of penance, the Eucharist, and anointing of the sick from non-Catholic ministers in whose churches these sacraments are valid (canon 844 §2).

Since the sacraments are valid in the Russian Orthodox church, under the appropriate conditions, outlined in the canon, Catholics could receive the sacraments in a Russian Orthodox church. Certainly traveling in Moscow and not able to find a Catholic church in union with Rome would meet those conditions.
