Two manganese(II) coordination polymers, [Mn 2 (bpt)(pa) 2 -(N 3 )] n [1; Hpa = picolinic acid, Hbpt = 3,5-bis(2-pyridyl)-4H-1,2,4-triazole] and [Mn 3 (ina) 2 (pa) 2 (N 3 ) 2 ] n (2; Hina = isonicotinic acid), have been synthesized by solvothermal treatment, in which the ligands bpt and pa were generated in situ by cyclocondensation and hydrolysis of 2-pyridylamidrazone, respectively. In 1, each binuclear subunit [Mn 2 (bpt)(N 3 )] bridged by bpt and N 3 -ligands is interlinked to four adjacent subunits via four tridentate pa ligands into a diamondoid 3D network, which shows spin-canting magnetism arising from

Azatriphenylene derivatives are of considerable interest due to their promising photophysical and coordinating properties [1] and to their presence in the composition of natural compounds [2,3]. Azatriphenylenes are important in inorganic biochemistry thanks to their use as intercalating ligands [4,5]. In addition, azatriphenylenes have shown promise as luminescent chemosensors of organic anions and nitroaromatic compounds [6].The most frequently used method for preparing azatriphenylenes is the Skraup synthesis [7,8] which demands the use of forcing conditions. Contemporary synthetic methods broadly use a cycloaddition reaction of hard to obtain alkenes or arylacetylenes with aromatic substrates catalyzed by transition metal salts [9,10]. Finally, the cyclocondensation of phenanthrenequinone with hydrazones of (hetero)aromatic carboxylic acid amides leads to the corresponding aryl- [11,12] and hetaryl-substituted [13] triazatriphenylenes.In this report, we propose an efficient method for the synthesis of cycloalkene-annelated derivatives of monoazatriphenylenes based on an aza-Diels-Alder reaction of the previously uncharacterized 3-(pyridin-2-yl)phenathro[9,10-e][1,2,4]triazine (1) [14] with 1-morpholinocycloalkenes. A method for preparing different pyridine derivatives through reaction of the corresponding mononuclear 1,2,4-triazines has been known for some time [15][16][17]. In our work, we have used this method for the first time in a single-stage synthesis of the poorly available pyridyl-substituted monoazatriphenylenes 2a,b.
