摘要：
Single crystals of two new modifications of [P(C6H5)(4)](2)[Cu2I4] were obtained by reaction of granulated copper with iodine and [P(C6H5)(4)]I in dry acetone under nitrogen atmosphere. They crystallise monoclinically, space group P2(1)/n (No. 14), a = 11.550(6), b = 7.236(2), c = 27.232(13) Angstrom, beta = 98.13(3)degrees V = 2253(2) Angstrom(3), and Z = 2 ([P(C6H5)(4)](2)[CU2I4]-C), and space group Cc (No.9), a = 17.133(5), b = 15.941(5), c = 18.762 (6) Angstrom, beta = 114.02(1)degrees, V = 4681(3) Angstrom(3), and Z = 4 ([P(C6H5)(4)](2)[Cu2I4]-D). respectively. In these compounds the [CuI2](-) anions form dimers di-mu-iodo-diiodocuprate(I), which are either planar (C) or folded (D).
