Eleven adducts from 4-methylbenzo[d]thiazol-2-amineand Carboxylic Acids via Classical H-bonds and Noncovalent Associations
Cocrystallization of4-methylbenzo[d]thiazol-2-amine with an array of carboxylic acids got a total of 11 crystalline adducts. The 11 adducts have been examined by XRD, IR and EA, the melting points of all adducts were also gauged.Their structural and supramolecular aspects are fully analyzed. The result reveals that among the investigated crystalline solids1-4, 6-7 and 9-10 the aryl N in thiazole cores are protonated when the organic acids are deprotonated and the crystal packing is interpreted by the strong charge-assisted N-H center dot center dot center dot O H-bond from the NH+ and the carboxylates. 5, 8 and 11 are cocrystals sustained by the neutral N-H center dot center dot center dot O/O-H center dot center dot center dot N H-bonds. Except the N-H center dot center dot center dot O H-bonds, the O-H center dot center dot center dot OH-bonds were also present at 3, 6, 7 and 9-11. 1 has the additional N-H center dot center dot center dot S H-bonds.The O-H center dot center dot center dot S H-bond was created in 10. 1 and 5 contained the N-H center dot center dot center dot N H-bond. 4 showed the N-H center dot center dot center dot Cl H-bond.Further analysis of the crystal packing of the adducts told that a different set of additional O-H center dot center dot center dot C,C-C,O-C, O-O, O-S,Cl-O, Cl-Cl, Cl-S, Br-Br,CH3-N, CH-O/CH2-O/CH3-O, CH3-Cl/CH-Cl, C-pi, CH3-CH3 CH3 -CH/CH-CH, NH-pi, CH3 -pi/CH2 -pi/CH- pi, Cl-pi and pi-pi – contacts contribute to the stabilization and expansion of the totalstructures. For the interplay of the various weak nonbonding contacts these structures took on homo/hetero supramolecular synthons.The recognition of the base-acid in all the multicomponent crystalsis based on thetypical R-2(2) (8) synthon. Due to the cooperation of these weak bonds,1-11 display 1D-3D motifs. (C) 2020 Elsevier B.V. All rights reserved.
