Space-group assignment is based on the low metric tensor distortion index for primitive orthorhombic determined by HKL-2000 and the presence of h = odd, k = odd and l = odd systematic absences in the h00, 0k0 and 00l directions, respectively. We do not yet know the exact number of molecules in the asymmetric unit. Values of 1, 2, 3 and 4 would yield solvent contents of 86.4, 72.8, 59.3 and 45.7%, respectively.
