Qatranaite (IMA No. 2016-024), Ca0.98Zn2.02(OH)6 · 2H2O, was found in spurrite pyrometamorphic rocks of the Hatrurim Complex, Jordan. It is monoclinic P21/c; a = 6.3786(3) Å; b = 10.9428(5)Å; c = 5.7511(3)Å; β = 101.95(1)º; V = 392.72(1)Å3; Z = 2. Raman spectroscopy reveled bands related to vibrations within Zn(OH)42- tetrahedra (cm-1): 297, 344 (ν2+ν4); 440, 449, 479 (ν1+ν3); 990 (Zn-O-Zn); 1065 (Zn-O-H); strong hydrogen bonds at 3497 and 3623 cm-1 (stretching vibrations O-H in OH groups) and weaker bands at ~2920, 3025, 3190 cm-1 (stretching vibrations O-H in HOH); very weak band at 1612 cm-1 (bending vibrations in HOH).
