COMPLEXES WITH SUBSTITUTED 2,5-DIHYDROXY-P-BENZOCHINONES AEC6X2O4.4H2O AE=CA2+, SR2+, X=CL, BR

In the isostructural compounds AEC//6X//2O//4 multiplied by (times) 4H//2O (AE equals Ca**2** plus , Sr**2** plus ; X equals Cl, Br) chains consisting of AE**2** plus and left bracket C//6X//2O//4 right bracket **2** minus are interlinked to layers by common water molecules. AE**2** plus has CN 8. In its coordination sphere there are 4 water molecules and 4 oxygen atoms of different left bracket C//6X//2O//4 right bracket **2** minus , which chelate AE**2** plus . On dehydration, the structure is destroyed. AE and X obviously influence disorder phenomena of water.
