王奎仁石（wangkuirenit.），理想式Pb.Cl2(Se4+O3)2，发现于意大利撒丁岛巴库鲁奇（b.ccy Rucci）铅-砷老矿山。该新矿物以板状或叶片状晶体产出，与其共生的矿物有兰硒铜矿、沃兰迪石、硒铅矾、铅矾和石英。王奎仁石在透射光下为很淡的黄色，晶体透明、具玻璃光泽，条痕为白色，性脆，其摩氏硬度约为3。沿（001）面的解理完全，未观察到有双晶或裂理。计算密度为6.48 g/cm3。根据电子探针分析结果和基于每个单元中有8个（O+Cl）原子获得王奎仁石的经验化学式为Pb..01Cl1.96(Se1.00O3.02)2。王奎仁石是与人工合成Pb.Cl2（Se O3）2相对应的天然矿物，与人工合成的Pb.b.2（SeO3）2和Pb.I2（SeO3）2具有相同的晶体结构。王奎仁石属单斜晶系，空间群为C2/c，晶胞参数为a=13.4266（4）,b.5.5826（2）,c=13.0024（4）?，β=94.287（2）o，V=971.87（5）?3,Z=4。王奎仁石晶体结构的特点具有平行于（001）面的Pb.+-(Se4+O3)2–结构层，层间靠阴离子Cl-相互连结起来。结构中一个非对称的单元内，存在有两种不同位置的的Pb.+阳离子（Pb.和Pb.）、一个(Se4+O3)2-阴离子团和一个Cl-阴离子。该Se4+阳离子与3个O原子相结合，形成(Se4+O3)2-三次配位。两个Pb.和Pb.均为8次配位，分别为[Pb.l2O6]和[Pb.l3O5]，阴离子O和Cl围绕Pb.和Pb.的分布表明，它们的6s2孤对电子是惰性的。王奎仁石是迄今记录到的6个铅的氯化物-亚硒酸盐矿物中的一个成员，在结构和成分上它与萨拉巴斯石[sarrab.sit.,Pb.CuC l4（SeO3）4]紧密相关。
