✦ Synopsis
A dark green, cube-shaped crystal of the bistrifluoroacetate of [22]porphyrin 1 suitable for X-ray structure analysis was obtained from CH2Cl,/TFA 40: 1 : CAD4 four-circle diffractometer (Enraf-Nonius), room temperature (Mo,, rddlation), 13025 reflections. Crystal data: space group P-1, u = 884.2(4), b = 1112.0(8), c = 1230.4(5)pm, OL =76.22(4), =74 18(4), 7 = 67.64(4)'. 2 = 1. Further details of the crystal structure investigation may be obtained from the Fachinformationszentrum Karlsruhe, Gesellschaft fur wissenschaftlich-technische Information mbH, W-7514 Eggenstein-Leopoldshafen 2 (FRG), on quoting the depository number CSD-54708, the names of the authors, and the journal citation.
