The two-dimensional network polymer of (ethanol)(μ₃-N-salicyclideneglycinato)nickel(II)

In the title complex, [Ni(C₉H₇NO₃)(C₂H₆O)]_n, each Ni atom is octa­hedrally coordinated by four O atoms and one N atom from three fully deprotonated N-salicylideneglycinate (salgly) anions and by one O atom from an ethanol mol­ecule. Two inversion-related Ni²⁺ ions are bridged by two O atoms from the phenolate groups of two salgly anions, forming a centrosymmetric dimeric unit which is further linked by carboxyl­ate O atoms to give a two-dimensional network coordination polymer in the bc plane.

Sulfachloro­pyridazine

In the title compound, 4-amino-N-(6-chloro-3-pyridazin­yl)­benzene­sulfonamide, C₁₀H₉ClN₄O₂S, the pyridazine ring and the benzene ring form a distorted V configuration, with a dihedral angle of 82.86 (6)°. The crystal packing is stabilized by π–π stacking inter­actions between the pyridazine rings and inter­molecular N—H...O, C—H...O and C—H...N hydrogen bonds, linking the mol­ecules into a two-dimensional network.

Methyl 12-bromo-13,14-dinitro­deisopropyl­dehydro­abietate

The title compound, C₁₈H₂₁BrN₂O₆, exhibits weak inter­molecular C—H...Br and C—H...O hydrogen bonds, which stabilize the structure. The title compound represents a new derivative of dehydro­abietic acid.
