In the title compound, C(19)H(17)BrN(2)O(2), the pyrazole ring makes dihedral angles of 88.00 (16) and 5.78 (13)° with the phenyl and bromo-phenyl rings, respectively. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds.
In the title compound, [Co(C(20)H(18)P)I(C(3)H(9)P)(2)], the Co(II) atom has a distorted square-pyramidal geometry, the base of which is comprised of two trans PMe(3) groups, an I atom, and a C atom of the benzyl group. This benzyl group is tethered to the P atom at the apex of the pyramid, thereby forming a five-membered chelated Co-C-C-C-P ring.
In the title compound, C(24)H(26)N(4)O(3), the pyrazolo[1,5-a]pyridine ring system makes dihedral angles of 38.130 (3) and 30.120 (3)°, respectively, with the isoxazole and phenyl rings. In the crystal, two mol-ecules are linked by a pair of C-H⋯N hydrogen bonds, forming a centrosymmetric dimer. A weak intra-molecular C-H⋯O inter-action is also present.
In the title mol-ecule, C(18)H(18)N(2)O(2), the bicyclic ring system and the benzene ring form a dihedral angle of 13.45 (3)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains propagated along .
