Alert level A PLAT601_ALERT_2_A Structure Contains Solvent Accessible VOIDS of . 206 A   3
Author Response: In the crystal structure, there is an 206 \%A^3^ void, but the low electron density (0.26 e.\%A^-3^) in the difference Fourier map suggests no solvent molecule occupying this void.

1 ALERT level A = Most likely a serious problem - resolve or explain 0 ALERT level B = A potentially serious problem, consider carefully 5 ALERT level C = Check. Ensure it is not caused by an omission or oversight 6 ALERT level G = General information/check it is not something unexpected 0 ALERT type 1 CIF construction/syntax error, inconsistent or missing data 4 ALERT type 2 Indicator that the structure model may be wrong or deficient 3 ALERT type 3 Indicator that the structure quality may be low 2 ALERT type 4 Improvement, methodology, query or suggestion 3 ALERT type 5 Informative message, check

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: S. Samshuddin, B. Narayana and H.S. Yathirajan - did the synthesis, crystalized the title compound and prepared the chemical sections of the manuscript. R. J. Butcher and S. Ozturk Y\?ild\?ir\?im - collected the XRD data, and solved and refined the crystal structure. M. Akkurt - checked the structure, drawn the scheme and figures, and prepared the manuscript.


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
