2 (01996 American Chemical Society Journal Of Medicinal Chemistry V39 Page 2835 Ma Supplemental Page 1 Experimental Data Collection 0183 Fvzos- A colorless rocks crystal of einyephg-having approximate dimensions of 0.30 x 0.20 x 0.10 mm was mounted on a glass fiber. All measurements were made on an Enraf-Nonius CAD4 diffractometer with filtered Cu-Ka radiation. Cell constants and an orientation matrix for data collection, obtained from a least-squares refinement using the setting angles of 25 carefully centered reflections in the range < 20 < corresponded to amonoclinic cell with dimensions: a = A b = A = c = A V = A3 For Z = 4 and F.W. = , the calculated density is 1.34 g/cm 3. Based on the systematic absences of: OkO: k # 2n packing considerations, a statistical analysis of intensity distribution, and the successful solution and refinement of the structure, the space group was determined to be: P2 1 (#4) The data were collected at a temperature of 25 j 1 0 C using the w scan technique to a maximum 20 value of Omega scans of several intense reflections, made prior to data collection, had an average width at half-height of with a take-off angle of Scans of ( tan 0)* were made at a speed of l6.5*/min (in omega). The weak reflections (I < 3.0o-(I)) were rescanned (maximum of 1 scans) and the counts were accumulated to ensure good counting statistics. Moving-crystal moving counter background measurements were made by scanning an additional 25% above and below the scan range. The counter aperture consisted of a variable horizontal slit with a width ranging from 2.0 to 2.5 mm and a vertical slit set to 2.0 mm. The diameter of the incident beam collimator was 0.7 mm and the crystal to detector distance wasm2+ cm. For intense reflections an attenuator was automatically inserted in front of the detector. Data Reduction Of the 2594 reflections which were collected, 2502 were unique (Rit = 0.033). The intensities of three representative reflection were measured after every 120 minutes of X-ray exposure time. No decay correction was applied. The linear absorption coefficient, p, for Cu-Ka radiation is 9.4 cm- 1. Azimuthal scans of several reflections indicated no need for an absorption correction. The data were corrected for Lorentz and polarization effects. A correction for secondary extinction was applied (coefficient = e-06). 2

The non-hydrogen atoms were refined anisotropically. Hydrogen atoms were included but not refined. The final cycle of fullmatrix least-squares refinement' was based on 1942 observed reflections (I > 3.00<r(I)) and 325 variable parameters and converged (largest parameter shift was 1.37 times its esd) with unweighted and weighted agreement factors of: R = ElIFo - Fc /EFo = R,; = V(Ew( Fo - IFcj) 2 /EwFo 2 )] = The standard deviation of an observation of unit weight 4 was The weighting scheme was based on counting statistics and included a factor (p = 0.005) to downweight the intense reflections. Plots of Ew(IFo - Fc ) 2 versus Fo, reflection order in data collection, sin 0/A and various classes of indices showed no unusual trends. The maximum and minimum peaks on the final difference Fourier map corresponded to 0.00 and 0.00 e-/v, respectively. Neutral atom scattering factors were taken from Cromer and Waber'. Anomalous dispersion effects were included in Fcalc 6 ; the values for Af' and Af' were those of Creagh and McAuley 7. The values for the mass attenuation coefficients are those of Creagh and Hubbel'. All calculations were performed using the texsan 9 crystallographic software package of Molecular Structure Corporation.

21 C01996 American Chemical Society Journal Of Medicinal Chemistry V39 Page 2835 Ma Supplemental Page 20 The ADC (atom designator code) specifies the position of an atom in a crystal. The 5-digit number shown in the table is a composite of three one-digit numbers and one two-digit number: TA (first digit) + TB (second digit) + TC (third digit) + SN (last two digits). TA, TB and TC are the crystal lattice translation digits along cell edges a, b and c. A translation digit of 5 indicates the origin unit cell. If TA = 4, this indicates a translation of one unit cell length along the a-axis in the negative direction. Each translation digit can range in value from 1 to 9 and thus -4 lattice translations from the origin (TA=5, TB=5, TC=5) can be represented. The SN, or symmetry operator number, refers to the number of the symmetry operator used to generate the coordinates of the target atom. A list of symmetry operators relevant to this structure are given below. For a given intermolecular contact, the first atom (origin atom) is located in the origin unit cell and its position can be generated using the identity operator (SN=1). Thus, the ADC for an origin atom is always The position of the second atom (target atom) can be generated using the ADC and the coordinates of the atom in the parameter table. For example, an ADC of refers to the target atom moved through symmetry operator two, then translated -1 cell translations along the a axis, +2 cell translations along the b axis, and 0 cell translations along the c axis. An ADC of 1 indicates an intermolecular contact between two fragments (eg. cation and anion) that reside in the same asymmetric unit. Symmetry Operators: (1) X, Y, Z (2) -X, 1/2+Y, -Z 22
