   0 ALERT level A = Most likely a serious problem - resolve or explain
   0 ALERT level B = A potentially serious problem, consider carefully
   3 ALERT level C = Check. Ensure it is not caused by an omission or oversight
   2 ALERT level G = General information/check it is not something unexpected

   0 ALERT type 1 CIF construction/syntax error, inconsistent or missing data
   1 ALERT type 2 Indicator that the structure model may be wrong or deficient

Alert level A
PUBL024_ALERT_1_A The number of authors is greater than 5.
              Please specify the role of each of the co-authors
              for your paper.
Author Response: Islor, Jagadeesh, Suresh Kumar, Ananda Kumari - synthesis, research and project settled around compound; Eric Hosten - mounting and selecting of crystals which was very time-consuming due to quality of sample; Thomas Gerber - initiator of this cooperation and supervisor of Xray facility; Richard Betz - structure solution and refinement as well as write up of this manuscript. NOTA BENE: I have already told the coworkers in India that this high number of co-authors and affiliaitons is absolutely NOT acceptable, and I have been promised that this would be an absolutely unique occurrence. 

   1 ALERT level A = Data missing that is essential or data in wrong format
   0 ALERT level G = General alerts. Data that may be required is missing
