Popis:	The single-crystal X-ray structure of gagarinite-(Ce) has been solved using a cleavage fragment taken from the type specimen of “zajacite-(Ce)”. The mineral is hexagonal, space group P 6 3 / m , with a 6.0861(12) and c 3.6810(8) A. It is isomorphous with gagarinite-(Y), with Ce 3+ dominating the REE site. The mineral name “zajacite-(Ce)” is discredited, and the mineral is renamed gagarinite-(Ce).
