CW EPR and optical absorption studies of Ni(II) ions doped in Zn(C₃H₃ClN₂)₆(ClO₄)₂ (Ni/ZCPC) were carried out at 300 K. The single crystal rotation along three orthogonal axes gave spin Hamiltonian parameters of g_x = 2.1961, g_y = 2.1679, and g_z = 2.1234; D_x = 1014.3, D_y = 913.7, and D_z = −1928.0 G. A progressive CW power saturation study performed at 300 K was used to determine the product of the electron spin–lattice relaxation time and spin–spin relaxation time (T₁ × T₂) (3.51 × 10⁻¹⁴ s²) for transitions at 4085 and 5740 G. Interestingly, the result demonstrates that Ni/ZCPC is a rare system having the largest T₁ × T₂ value observed at 300 K compared to other Ni(II) systems reported to date. The optical and EPR data were used to obtain the bonding parameters. The EPR spin Hamiltonian parameters and deconvolution of the optical absorption spectrum reveal that the Ni(II) center has trigonal symmetry.

掺杂在 Zn(C ₃ H ₃ ClN ₂ ) ₆ (ClO ₄ ) ₂ (Ni/ZCPC) 中的 Ni(II) 离子的 CW EPR 和光吸收研究在 300 K 下进行。沿三个正交轴的单晶旋转得到自旋哈密顿参数 g _x  = 2.1961，g _y  = 2.1679，g _z  = 2.1234；D _x  = 1014.3、D _y  = 913.7 和 D _z  = -1928.0 G。在 300 K 下进行的渐进 CW 功率饱和研究用于确定电子自旋-晶格弛豫时间和自旋-自旋弛豫时间的乘积（T ₁  × T ₂）（3.51×10 ^-14小号²），用于在跳变和4085 5740 G.有趣的是，结果表明，镍/ ZCPC是具有最大T A罕见系统₁  ×T ₂在300K测量值相对于其他的Ni（II ) 迄今为止报告的系统。光学和 EPR 数据用于获得粘合参数。EPR 自旋哈密顿参数和光吸收光谱的解卷积表明 Ni(II) 中心具有三角对称性。
