چکیده

In the crystal structure of the title compound, C(25)H(30)N(2)O(4), the steric size of the tert-butyl group causes the 3,5-dimethyl-phenyl ring to adopt a transoid geometry with respect to the N-C(O) bond. The six-membered heterocyclic ring is disordered over two sites, with occupancies of 0.553 (4) and 0.447 (4). Intra-molecular C-H⋯O inter-actions are present. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds.

In the title mononuclear complex, [Ru(C14H20O2)2(C10H8N2)], the RuII ion has a distorted octa-hedral coordination environment defined by two N atoms of the chelating 2,2'-bi-pyridine ligand and four O atoms from two 3,5-di-tert-butyl-o-benzo-quinone ligands. In the crystal, the complex mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds and π-π stacking inter-actions between the 2,2'-...

In the title mol-ecule, C(30)H(36)N(2)O(2), the dihedral angles between the central benzene ring and the two benzene rings of the butyl-salicylaldimine groups are 14.3 (2) and 40.6 (2)°. There are two strong intra-molecular O-H⋯N hydrogen bonds which form S(6) rings. The crystal studied was a non-merohedral twin with refined components of 0.270 (4) and 0.730 (4).

The asymmetric unit of the title compound, C(47)H(58)N(6)O(6), comprises three independent mol-ecules, in one of which one tert-butyl group is disordered in a 1:1 ratio. The mol-ecule is a di(ar-yl)methane having two aliphatic and one N-heterocyclic substituent in each aryl ring. For the mol-ecule having the disordered tert-butyl group, the aryl rings make an angle of 115.3 (2)° at the methyl-e...
