(6d) and (cha)[(MeO)2DHAP(Ph)] (6e): The data for
6d were numerically corrected for absorption with the
use of XPREP.20 One of the methylene H atoms in 6d
was refined with Uiso(H-1A) = Ueq(C-1). All H atoms
in 6e were found in difference Fourier maps. In the final
refinement cycles, all N- and C-bonded H atoms were

The hydroxyl H-3 atom was refined isotropically. In 6b
and 6e, the extinction was also refined; the final extinc-
tion coefficient was 0.0049(10) in 6b and 0.00132(18) in
6e.

Na2[(MeO)2DHAP]Æ5.75H2O (6c): One of the water
molecules is disordered into three positions denoted as
O-5W, O-51W and O-52W. Initial refinement stages
revealed that the sum of occupation factors of these
positions is close to 0.75. Therefore, in the final refine-
ment cycles, the s.o.f. for the individual positions were
refined, but the sum of site occupation factors was
restrained to be constant and equal to 0.75(1). In the
model finally accepted, the s.o.f. for the respective posi-
tions were 0.38(2) for O-5W, H-9W, H-10W; 0.25(1) for
O-51W, H-09W, H-01W and 0.12(2) for O-52W. The H
atoms from disordered O-5W and O-51W positions were
found in difference-Fourier maps and were refined with
Uiso(H) = 1.5Ueq(O). Those from O-52W position were
not even found.
