RemarksR=0.050000 : MIN =Zeolite X : DEF
The coordinates are those given in the paper but the atomic distances do not agree with those calculated during testing.The coordinates are probably correct.
Mean T-O: 1.61, 1.745, H added for charge compensation, exchanged in AgNO3 solution for 3 d, heated to 673 K and rehydrated at RT, cell as for hydrated form before heating
