Full structure resolution of the solvent molecule in 6·pentane,
presumed to be a pentane fraction from light petroleum, proved
impossible due to its highly disordered nature. Five carbon atoms
were located in difference maps, two of which have been modelled
over two positions, to form a straight alkyl chain. All carbon atoms
were modelled anisotropically. The hydrogen atoms have not been
modelled but have been included in the formula. A low cut-off
value for theta was used due to there being no reliable/significant
intensity data beyond this value.

25 Here there is also a short C–H ◊ ◊ ◊ F interaction from a dimethylamide
methyl group to the opposite o-F atom of the same C6F5 ring, C(33)–
˚
H(33c) ◊ ◊ ◊ F(76) (2.34(2) A).

27 There are no close intramolecular C–H ◊ ◊ ◊ F interactions as observed
˚
in 4.CH2Cl2 but there is a short intermolecular interaction (2.37 A)
between one of the pyrazolyl methyl group hydrogen atoms and the
m-F of a C6F5 ring on a symmetry related molecule. The two molecules
are related by the symmetry operation x - 1, y, z.

28 In one instance, adventitious water was introduced during the at-
tempted synthesis of 6, resulting in the precipitation of a yellow
crystalline solid. Poor solubility precluded spectroscopic analysis but
elemental analysis was consistent with the formulation as the hydrolysis
product {Tp*Zr(NMe2)2}2{m-O}. Elemental analysis found: C 47.0, H
6.9, N 23.0. Calculated for C38H68B2N16OZr2: C 47.1, H 7.1, N, 23.1.
