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, Malladi, Telkar - 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

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
