We prepared two new phases of high-T-c superconductors with water molecules as the main constituents of the charge-reservoir block and refined the synthesis method for another phase. These water containing phases form from high-pressure-synthesized Sr2Can-1CunO2+2n +/-delta or 0((sr))2(n-1)n (n = 2-4) superconducting phases through a topotactic water-intercalation process when the parent phases are exposed to open air at 80 degrees C. Upon the water intercalation the body-centered unit cell of the parent phase is elongated along the c-axis direction by similar to 6.2 angstrom. Despite the elongated unit cell the T-c value is not changed upon the water intercalation. The water-based H-m((sr))2(n-1)n copper-oxide superconductors are new exotic members of the yet tiny family of superconductors with T-c values higher than 100 K. (C) 2016 Elsevier B.V.
