초록

[ $cis-[Co(13-aneN_4)(N_3)_2]Cl{\cdot}H_2O$ ] (1) (13-ane$N_4$ = 1,4,7,10-tetraazacyclotridecane) 착물(錯物)을 합성(合成)하고 구조(構造)를 규명(糾明)하였다. 이 착물(錯物)은 단사정계(單斜晶系), 공간군(空間群) Pbca, a = 7.8282(4) ${\AA}$, b = 14.3197(7) ${\AA}$, c = 29.9021(15) ${\AA}$, V= 3351.9(3) ${\AA}^3$, Z = 8로 결정화(決定化) 되었다. 착물(錯物) 1의 코발트(III)이온은 거대(巨大)고리 리간드의 4개(個)의 질소원자(窒素原子)와 시스 위치에 2개(個)의 azide 리간드가 결합(結合)한 고천(若干) 일그러진 팔면체(八面體) 구조(構造)를 갖는데, 착물(錯物)의 양이온, 염소(鹽素) 음이온 및 물분자(分子)를 통하여 1차원의 수소결합(水素結合)을 형성(形成)한다.

The complex $cis-[Co(13-aneN_4)(N_3)_2]Cl\cdot H_2O$ (1) (13-ane$N_4$ = 1,4,7,10-tetraazacyclotridecane) has been synthesized and structurally characterized by X-ray crystalloaraphy. It crystallizes in the orthorhombic system Pbca, a = 7.8282(4) ${\AA}$, b = 14.3197(7) ${\AA}$, c = 29.9021(15) ${\AA}$, V = 3351.9(3) ${\AA}^3$, Z = 8. The cobalt(III) ion in 1 is coordinated to four nitrogen atoms from the macrocycle and two azide ligands of cis position in a distorted octahedral environment, which forms the 1D polymer through hydrogen bonding contacts involving the cation, chloride anion and solvent water molecules.
