Abstract

Crystal structure of Bis(N-Methylphenazinium)-Tetracyanopalladate(II) hydrate has been determined by X-ray crystallography. Crystal data: $(C_{13}H_{11}N_2){_2}[Pd(cn)_4]{\cdot}H_2O$, Monocline, Space group $P2_1/b$(No=14), a=9.783(4), b=10.788(4), c=13.666(4) ${\AA},\;{\beta}=104.59(5),\;Z=2,\;V=1392.9{\AA}{^3},\;Dc=1.476gcm^{-3},\;F(000)=632,\;{\mu}=7.05cm^{-1}$. The structure was solved by Patterson method and refined by full matrix least-square methods using unit weights. The final R and S values were R=0.0257, Rw=0.0732, Rall=0.0283 and S=1.07 for 1930 observed reflections. Both cation and anion complexes are essentially planar and have dihedral angles of $10.16(4)^{\circ}$. The planar complex anions are sandwiched between slightly bent cations. The interplanar separations in one triad and between two triads are 3.419(3) and $3.402(4){\AA}$, respectively. The triads are stacked along b-axis.

Bis(N-Methylphenazinium)-Tetracyanopalladate(II) Hydrate $(C_{13}H_{11}N_2){_2}[Pd(CN)_4]{\cdot}H_2O$의 단위 착이온 및 결정의 구조들을 X-선 회절법으로 연구하였다. 이 결정은 사방정계이고 공간군은 $P2_1/b$(군번호=14)이다. 단위세포 a=9.783(4), b=10.788(4), c=13.666(4) ${\AA},\;{\beta}=104.59(5),\;V=1392.9{\AA}{^3},\;Z=2,\;Dc=1.476gcm^{-3},\;F(000)=632,\;{\mu}=7.05cm^{-1}$이다. 구조분석은 중금속법으로 풀었으며, 최소자승법으로 정밀화 하였고, 최종 신뢰도 값들은 1930 회절반점에 대하여 R=0.0257, Rw=0.0732, Rall=0.0283 및 S=1.07 이었다. 두 이온들은 근본적인 평면구조로써, 이들의 충진구조는 착음이온을 두개의 양이온들이 거의 평행하게 둘러싸고 있는 삼중체들을 형성하고 있다. 양이온과 음이온들의 이면각은 $10.16(4)^{\circ}$인 삼중체들이 b축을 따라서 배열되어 있다, 삼중체내 및 삼면체간의 면간 거리들은 3.419(3)와 $3.402(4){\AA}$이었다.
