1.Crystal structure of (2-{[3,5-bis-(1,1-di-methyl-eth-yl)-4-hy-droxy-phen-yl](5-methyl-2H-pyrrol-2-yl-idene)meth-yl}-5-methyl-1H-pyrrolido-κ(2) N,N')di-fluoridoboron.

The title compound, C25H31BF2N2O, is a potential boron tracedrug in boron neutron capture therapy (BNCT), in which the B atom adopts a distorted BN2F2 tetra-hedral geometry: it is soluble in dimethyl sulfoxide, di-methyl-formamide and methanol. The pyrrolyl-idene-methyl-pyrrole triple fused ring system is almost planar (r.m.s. deviation = 0.031 Å) and subtends a dihedral angle of 47.09 (5)° with the plane of the pendant phenol ring. The phenol -OH group is blocked from forming hydrogen bonds by the adjacent bulky tert-butyl groups. In the crystal, inversion dimers linked by pairs of very weak C-H⋯F inter-actions generate R 2 (2)(22) loops.

In the title compound, C14H9Cl2N3O4·C3H7NO, the hydrazone mol-ecule adopts an E conformation with respect to azomethine bond, and the dihedral angle between the two aromatic rings [8.96 (11)°] shows that the rings are almost co-planar. The planar conformation of the mol-ecule is stabilized by the intra-molecular O-H⋯N hydrogen bond involving the OH group and azomethine N atom. The azomethine and keto bond distances [1.269 (2) and 1.210 (2) Å, respectively] are very close to the formal C=N and C=O bond lengths. The di-methyl-formamide solvent mol-ecule is connected to the hydrazone NH group via an N-H⋯O hydrogen bond. In the crystal, non-classical C-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into chains along [322]. A supra-molecular three-dimensional architecture is created by weak C-Cl⋯π [4.163 (3) Å, 83.26 (9)°] and π-π [centroid-centroid distance = 4.0395 (14) Å] inter-actions.

The structure of the polymeric title compound, {[Zn2(C20H11NO4)2(C3H7NO)2(CH3OH)]·C3H7NO} n , comprises carbazolylisophthalate moieties connecting dimetallic tetra-carboxyl-ate zinc secondary building units (SBUs) parallel to [100] and [010], leading to a layer-like arrangement parallel to (001). Each SBU consists of two Zn atoms in slightly distorted tetra-hedral and octa-hedral coordination environments [Zn⋯Zn = 3.5953 (6) Å]. Three carboxyl-ate groups bridge the two Zn atoms in a μ2-O:O' mode, whereas the fourth coordinates through a single carboxyl-ate O atom (μ1-O). The O atoms of two di-methyl-formamide (DMF) and one methanol mol-ecule complete the Zn coordination spheres. The methanol ligand inter-acts with the noncoordinating DMF mol-ecule via an O-H⋯O hydrogen bond of medium strength. Carbazoles between the layers inter-digitate through weak C-H⋯.π inter-actions to form a laminar solid stacked along [010]. Two kinds of C-H⋯π inter-actions are present, both with a distance of 2.

The title compound, [Mo(C14H9BrN2O2)O2(H2O)]·C3H7NO, has a distorted octa-hedral geometry around the Mo atom, with the two terminal oxide groups lying cis to each other. The two aromatic rings present in the mol-ecule are almost coplanar, forming a dihedral angle of 1.4 (2)°. The five-membered ring involving the metal atom is puckered, with an amplitude Q = 0.358 (2) Å and ϕ = 204.1 (6)°. In the crystal, pairs of inversion-related mol-ecules are linked by O-H⋯N hydrogen bonds. An O-H⋯O hydrogen bond connects the water ligand to the di-methyl-formamide solvent mol-ecule. The crystal packing also features π-π [centroid-centroid distance of 3.688 (2) Å] and C-H⋯O inter-actions.
