parameters a = 5.6184(3) Å, b = 15.2744(6) Å, c = 6.9202(3) Å, α = 90°, β = 102.864(2)°, γ = 90°. These are neutral complexes, in which molecules are only connected by van der Waal's interactions. Thermal gravimetric analyses (TGA) have shown that 3 and 4 evaporate practically without decomposition. MOCVD experiments were carried out at lower pressure using 3 and 4 as precursors. The films were grown
((CH3)2Au)2C2O4(1)、((CH3)2AuSCN)2(2)、(CH3)2AuSSP(OCH3)2(3)和(CH3)2AuSSP(OC2H5)2(4)的制备和重结晶从己烷中确定其晶体结构并通过热法 (TGA) 对其进行分析。这些化合物已被研究作为金属有机化学气相沉积 (MOCVD) 的新的可能前体。化合物 1 和 2 是固体,而化合物 3 和 4 是液体。通过单晶 X 射线衍射 (XRD) 研究了 1 和 2 的晶体结构:化合物为单斜晶系,空间群为 1 P21/c,为 2 P21/n。化合物1的晶体参数a = 7.6952(5) Å, b = 11.1814(8) Å, c = 12.2893(8) Å, α = 90°, β = 104.922(4)°, γ = 90°;2 具有晶体参数 a = 5.6184(3) Å, b = 15.2744(6) Å, c = 6.9202(3)
