SERVICE MEASUREMENT

Sample collection

  • in room NC 2/91, contact person: Bert Mallick, room NC 2/73
  • fill in the measurement order form
  • Please indicate the structure of the possible product as well as the solvents and starting materials used on the measurement order.

Air-stable samples can be handed in directly and will be measured at the next possible date.

Air-sensitive samples:

  • please arrange an appointment
  • we will provide you with a slide containing perfluorinated polyether, which you can insert into the glovebox and embed the crystals in it
  • most substances are air-stable in this ether for at least 10 minutes and are thus protected for the time of crystal preparation
  • we try to select the best possible crystal to obtain publishable data. However, we cannot give a guarantee

After the measurement

    after the measurement you will receive a complete cif-file including IUCR-checkcif
    if desired, we load the data into the CCDC, you will then also receive a CCDC deposit number. Please note that you still send us the bibliographic data after the publication of the structure, so that we can complete the deposited cif-file accordingly. After one year, the data without bibliographic information will be filed as 'private communication'.


SELF-MEASUREMENT

The instruments may only be used by persons who have the following requirements:

  • sufficient crystallographic knowledge
  • personal instruction in the use of the equipment
