Copper(I) complexes with N-(p-nitrophenyl)-N′-alkoxycarbonylthiourea:: Syntheses and crystal structures of [Cu(H2net)2Cl] • CH2Cl2 and [Cu(H2nmt)2Cl]2 • (CHCl3)2

Two copper(I) complexes, [Cu(H(2)net)(2)Cl]. CH2Cl2 (1) and [Cu(H(2)nmt)(2)Cl](2).(CHCl3)(2) (2), were synthesized by the reaction of CuCl2. 2H(2)O with N-(p-nitrophenyl)-N'-(ethoxycarbonyl)thiourea (H(2)net) and N-(p-nitrophenyl)-N'-(methoxycarbonyl)-thiourea(H(2)nmt), respectively. Both complexes crystallize in the monoclinic space group C2/c. For complex 1, a=29.52(2), b=13.920(6), c=14.873(3)Angstrom; beta=101.75(2)degrees, V=5984(4) Angstrom(3), Z=8 and R=0.053 for complex 2, a=30.68(1), b=13.369(4), c=14.226(7) Angstrom, beta=99.52(4)degrees, V=5754(4)Angstrom(3), Z=4 and R=0.063. Tn complex 1, two H(2)net molecules are bonded to Cu(I) atom through two S atoms forming a mononuclear complex with trigonal geometry for the Cu(I) ion [CI(1)-Cu-S(1)=118.54(7), Cl(1)-Cu-S(2)=119.70(7), S(I)-Cu-S(2)=112.17(8)degrees, Cu-S(1)=2.251(2), Cu-S(2)=2.255(2), Cu-Cl(1)=2.263(2) Angstrom]. Complex 2 is a dimer formed by long Cu-S inter actions [Cu-S*=2.607(3) Angstrom] from adjacent two H(2)nmt molecules; the Cu(I) ion has distorted tetrahedral coordination [Cl(1)-Cu-S(1)=119.8(1), Cl(1)-Cu-S(2)=120.0(1), S(1)-Cu-S(2)=108.85(9)degrees] with unequal Cu-S [2.268(2), 2.247(2) Angstrom] and Cu-CI(1) [2.255(2) Angstrom] bonds.
