A revised structure for α-dicalcium silicate hydrate
The structure of α-dicalcium silicate hydrate, Ca_2(SiO_3OH)(OH), has recently been described and refined [Y ano, Urabe, Ikawa, Teraushi, Ishizawa & Udagawa (1993). Acta Cryst. C49, 1555-1559] in space group P2_12_12_1 (orthorhombic; a = 9.487 (4), b = 9.179 (4), c = 10.666 (7) Å, Z = 8). It is better described in Pbca. Revised coordinates are given.
