 Sent to CCL by: "Ramachandran  Chelat" [rcchelat**rediffmail.com]
 Dear CCL friends,
 I am looking for the coordinates for Structure I and Structure II in which gas
 hydrates are forming.  Can you please help me to get coordinates or references
 of the same  for a unit cell of these structures
 Thanks in advance
