The coordination of heterocyclic thiourea ligands (L = N-(2-pyridyl)-N´-phenylthiourea (1), N-(2-pyridyl)-N´-methylthiourea (2), N-(3-pyridyl)-N´-phenylthiourea (3), N-(3-pyridyl)-N´methylthiourea (4), N-(4-pyridyl)-N´-phenylthiourea (5), N-(2-pyrimidyl)-N´-phenylthiourea (6), N-(2-pyrimidyl)-N´-methylthiourea (7), N-(2-thiazolyl)-N´-methylthiourea (8), N-(2benzothiazolyl)-N´-methylthiourea (9), N,N´-bis(2-pyridyl)thiourea (10) and N,N´-bis(3pyridyl)thiourea (11) with CuX (X = Cl, Br, I, NO3) has been investigated. CuX:L product stoichiometries of 1:1-1:5 were found, with 1:1 being most common. X-ray structures of four 3coordinate mononuclear CuXL2 complexes (CuCl(6)2, CuCl(7)2, CuBr(6)2, and CuBr(9)2) are reported. In contrast, CuBr(1)2 is a 1D sulfur-bridged polymer. CuIL structures (L = 7, 8) are 1D chains with corner-sharing Cu2(-I)2 and Cu2(-S)2 units, and CuCl(10) is a 2D network having -Cl and N-/S-bridging L. Two [CuL2]NO3 structures are reported: a mononuclear 4-coordinate copper complex with chelating ligands (L = 10) and a 1D link-chain with N-/S-bridging L (L = 3). Two ligand oxidative cyclizations were encountered during crystallization. CuI crystallized with 6 to produce zigzag ladder polymer [(CuI)2(12)]•2CH3CN (12 = N-(pyrimidin-2yl)benzo[d]thiazol-2-amine) and CuNO3 crystallized with 10 to form [Cu2(NO3)(13)2(MeCN)]NO3 (13 = dipyridyltetraazathiapentalene).
