Single crystals of the previously unknown potassium calcium silicate K2Ca4Si8O21 (1) have been grown from a nonstochiometric melt as well as using a KCl flux. The compound is triclinic with the following basic crystallographic data: space group P, a = 6.8052(3) A, b = 7.1049(3) A, c = 11.2132(5) A, alpha = 96.680(4)degrees, beta = 105.280(4) degrees, gamma… CONTINUE READING
