Abstract

The complex [Zn(L)₂(H₂O)₄] (1) (L = isonicotinate) has been prepared and characterized by X-ray crystallography. Compound 1 crystallizes in the triclinic space group P1, with a = 6.9062(4) , b = 9.2618(7) , c = 6.3313(3) , α = 104.986(6)°, β = 112.865(4)°, γ = 96.213(6)°, V = 350.41(4) , Z = 1, R₁(wR₂) for 1225 observed reflections of [I > 2σ(I)] was 0.0209 (0.0591). The coordination environment of the zinc atom can be described as an octahedron in which the isonicotinato ligands are mutually trans. Compound 1 is also connected into a two-dimensional chain via hydrogen-bonds.

[Zn(L)₂(H₂O)₄] (1) (L = isonicotinate) 착물을 합성하고 구조를 규명하였다 이 착물은 삼사정계, 공간군 P1, a = 6.9062(4) , b = 9.2618(7) , c = 6.3313(3) , α = 104.986(6)°, β = 112.865(4)°, γ = 96.213(6)°, V : 350.41(4) ³, Z = 1로 결정화 되었다. 이 착물의 구조는 최소자승법으로 정밀화하였으며, 최종신뢰도 R₁(wR₂)값은 1225개의 회절반점에 대하여 0.0209및 0.0591이었다. Zn 원자의 배위환경은 isonicotinate 리간드가 서로 trans에 위치한 팔면체 구조를 갖는다 . 또한 화합物 1은 수소결합에 의한 이차원의 사슬 구조로 연결되어 있다
