<p>Kalyuzhnyite-(Ce), ideally NaKCaSrCeTi(Si<span>8</span>O<span>21</span>)OF(H<span>2</span>O)<span>3</span>, is a new mineral from the Darai-Pioz alkaline massif, Tien-Shan mountains, Tajikistan. It occurs as equant grains up to 0.05 × 0.07 mm in a quartz–pectolite aggregate in a silexite-like peralkaline pegmatite. Associated minerals are quartz, fluorite, pectolite, baratovite, aegirine, leucosphenite, neptunite, reedmergnerite, orlovite, sokolovaite, mendeleevite-(Ce), odigitriaite, pekovite, zeravshanite, kirchhoffite and garmite. The mineral is colourless with a vitreous lustre and a white streak, and <span>D</span><span>calc.</span> is 3.120 g/cm<span>3</span>. Kalyuzhnyite-(Ce) is monoclinic, <span>P</span>2/<span>c</span>, <span>a</span> = 18.647(4), <span>b</span> = 11.214(2), <span>c</span> = 14.642(3) Å, β = 129.55(3)° and <span>V</span> = 2360.9(11) Å<span>3</span>.
