Abstract
Mo2O4Cl2(X-py)4·2H2O와 (X-pyH)4(Mo2O4(NCS)6)]·H2O를 합성하고 이들 착물에 대한 자기적 및 분광학적성질을 조사하였다. Mo2O4Cl2(X-py)4·2H2O (X-py=3-및 4-시아노피리딘, 2-및 4-아미노피리딘, 니코틴아미드, 3,5-루티딘 및 2-아미노-4-피코린)은 옥소오클로로몰리브덴(Ⅴ)산 치환피리딘늄을 가수분해시켜 얻었다. 또한, MoO(NCS)3에 물과 치환피리딘류를 가하여 갈색의 (X-pyH)4[Mo2O4(NCS)6]·H2O를 얻었다. 여기서 X-py는 피리딘, α-피코린, 3-브로모피리딘, 3,5-루피린, 3-벤조일피리딘 및 4-아세틸피리딘이다. Mo2O4Cl2(X-py)4·2H2O와 (X-pyH)4[Mo2O4(NCS)6]·H2O는 반자성을 가진 이합체로서 Mo2O4Cl2(X-py)4·2H2O는 비전해질이나 (X-pyH)4[Mo2O4(NCS)6]·H2O는 전해착물임을 알았다.

Mo2O4Cl2(X-py)4·2H2O and (X-pyH)4(Mo2O4(NCS)6)]·H2O have been prepared. The infrared, electronic and reflectance spectra, molar conductances and magnetic susceptibility data of complexes are reported. Mo2O4Cl2(X-py)4·2H2O (X-py were 3-and 4-cyanopyridine, nicotinamide, 3,5-lutidine and 2-amino-4-picoline) were obtained by hydrolysis of the corresponding substituted pyridinium oxopentachloromolybdates(Ⅴ). Addition of water and substituted pyridines to molybdenum(Ⅴ)-thiocyanate ethylacetate extract yielded brown compounds, (X-pyH)4[Mo2O4(NCS)6]·H2O where X-py were pyridine, α-picoline, 3-bromopyridine 3,5-lutidine, 3-benzoylpyridine and 4-acetylpyridine. Binuclear, Mo2O4Cl2(X-py)4·2H2O prepared from hydrolysis of (X-pyH)2[MoOCl5]·H2O were diamagnetic and nonelectrolytes. The anion of (X-pyH)4[Mo2O4(NCS)6]·H2O was formulated as dimer and electrolyte.
