Ushbu tadqiqotda [Zn(INA)₂(DMF)(H₂O)]ₙ formulali Zn(II)-asosidagi koordinatsion polimerning sintezi, kristall tuzilishi, termik barqarorligi hamda adsorbsiya xossalari bayon etilgan. Yakka kristalli rentgen difraksiyasi tahlili moddaning nosentrosimmetrik monoklinik Ia fazoviy guruhida kristallanishini ko‘rsatdi va natijada qutbli hamda strukturaviy jihatdan barqaror karkas hosil bo‘lishi aniqlandi. Tuzilma Zn(II) markazlarining izonikotinat ligandlari orqali karboksilat kislorod atomlari va piridin azot donor atomlari yordamida o‘zaro bog‘lanishi natijasida shakllanib, π–π stacking va vodorod bog‘lanishlari kabi supramolekulyar o‘zaro ta’sirlar bilan barqarorlashgan kengaytirilgan polimer tarmoq hosil qiladi. Batafsil poliedral tahlil deyarli ideal tetraedrik va buzilgan koordinatsion geometriyalarning birgalikda mavjudligini ko‘rsatdi, bu esa Zn(II) ionining strukturaviy moslashuvchanligini aks ettiradi. Termik tahlil (TGA/DTA) uch bosqichli parchalanish jarayonini ko‘rsatdi, bunda erituvchining yo‘qolishi, ligandning parchalanishi va yakunda ZnO qoldig‘ining hosil bo‘lishi kuzatildi, bu esa o‘rtacha termik barqarorlikni tasdiqlaydi. Azot adsorbsiya-desorbsiya tadqiqotlari gisterezisli IV-tip izotermani ko‘rsatdi, bu esa mezog‘ovakli materiallarga xosdir. Ushbu birikma 24.34 m²/g solishtirma sirt maydoniga va 7.515 × 10⁻² cm³/g umumiy g‘ovak hajmiga ega bo‘lib, g‘ovak o‘lchamlarining taqsimoti mezog‘ovak sohada (~3.6–3.8 nm) markazlashgan. Olingan natijalar Zn-asosidagi koordinatsion polimerlarda koordinatsion muhit, strukturaviy topologiya va adsorbsiya xatti-harakatlari o‘rtasidagi o‘zaro bog‘liqlikni yoritib beradi.
