Annotatsiya: Ilk bor 2-amino-1-metilbenzimidazol (MAВ) va La(III) nitratining tarkibi [La(NO3)6][(MAB-H)]3 bo‘lgan yangi kompleks birikmasi sintez qilingan. Olingan kompleks birikmaning tarkibi va tuzilishi element, termogravimetrik, IQ-spektroskopiya va rentgenostrukturaviy tahlil usullari yordamida o‘rganilgan. N-protonlangan 2-amino-1- metilbenzimidazoliy kationlari va nitrat anionlarini o‘z ichiga olgan kompleks [La(NO3)6][(MABH)] 3 monoklinik singoniyaga ega bo‘lib, fazoviy guruhi P21 /c. Kompleks birikmaning struktur tuzilishida La atomi buzilgan ikosaedral poliedrda o‘n ikki koordinatsiyali tuzilishga ega ekanligi, [La(NO3)6]3- anionning nitrat qismlaridagi kislorod atomlari va imidazoliy halqasidagi protonlangan azot kationlari o‘rtasida bir nechta N-H....O vodorod bog‘lari mavjud ekanligi aniqlangan. Sintez qilingan [La(NO3)6][(MAB-H)]3 birikmaning Xirshfeld sirt tahlilida O···N/N···O, H∙∙∙H ва О∙∙∙H/Н∙∙∙О ta’sirlari ko‘proq kuzatilgan hamda molekulalararo ta’sirlashish energiyalari aniqlangan. Kristalli qadoqning mustahkamligini tekshirish uchun bo‘shliq tahlili o‘tkazilgan
